Welcome to the thread Barry70GTX..
Good to see another 57Hemi swap going. There's only a few us known to exist right now. This is new territory for all of us. I see you grabbed a salvage engine/trans. I have a salvage engine as well (no trans). I'm going to use the 904 trans that I have. I was planning on using the tremec (Keisler) later on. Recently, I found another trans that sounds interesting. It's a beefed-up A518 (4spd OverDrive) with lock-up torque converter. The lock-up converter can be set up with pressure switches to shift in/out of OD automatically. No need for a trans computer.

I got my old belt from a car repair shop, the dealer had a couple but they were for warranty replacement and they couldn't give it to me yet. I don't think it matters whether its a 6 or 7 belt.

Oooh, that's scary, I'm out front! There's a few that have done this prior to me but I'm been pretty vocal about issues I've encountered, more to see what others think about it than complaining, sorry if it comes over as bitching.

I thought the intake was painted but I remember your setup now. What's funny is I've got a crate, you have a takeout with a 904, the other guy here (sorry don't remember name) has the full hemi/5speed auto transplant, whiteboy has a takeout/kessler, and the new guy has a 6.1 takeout. We're all doing it different.

In other news, I picked up the 727 today complete with the modified hemi flexplate (cut off ring gear and slotted hole for the offset bolt). Worked on the Cuda a bit removing stuff like wheels, exhaust, and other extras and cleaning underneath.

Anyone need a slant 6 electronic ignition conversion kit? Pulled one off and don't need it anymore.

-Daty

The new hemi in the old a'body is going to be the hot ticket, in my opinion. From everything I have read the new hemi is a great motor in a smallish package, and with a 5 speed and some swaybars will make just about any a'body quite a roadwarrior.

I hope to be doing this very same project sometime in the near future.

Good luck trailblazer.

I was at Ennis Sunday and my buddies Hemi truck ran 15.2, a Magnum (complete with baby seat) ran 14.5, and a Charger ran 14 flat. They weigh 5000, 4500, and 4100 respectivly. With an A-body in the 3-3500 range depending, add TTIs for another 40hp and we're talking low 13/high 12s depending on the chassis. What is really cool is they weigh as little as a slant 6, it's lower and shorter than a 340, can pull 20 inches of vaccumn and top 6900 rpm without the rev limiter. Like you said Cogz it's not the 1/4 mile where this package will shine but on the street. It's a drag you can't have power steering with the A-Body/TTI setup, I've got a 16:1 manual box (huge difference from a 24:1), FF front bar, and 4 wheels disks (12" front, 11" rear). What a package!

-Daty

Not only the headers, but also check out the recent hotrod mag article where they did a cam swap in addition to the headers. I believe they got well over 400hp without touching the heads. I can't speak to the upper limits of this motor, but as far as I am concerned, its the first mopar killer smallblock. (at least on stock shortblock)

I am toying with the idea of buying a beater 66'ish a'body to start fittment, and see if I can fit twin turbos in there somewhere. They do it with 5.0 mustangs which are about a'body size... why not go twin turbo Mopar?

Daty,
You mentioned something I had a question about. The flexplate. What flexplate do you think I would be using with a 904 trans? The same one you mentioned?

Also, Street & Performance has a Fuel Pump/Filter setup they use with their Hemi swaps. Have you seen it? Do you know if it will work with a Crate Engine or is it more for the stock engine?

Sorry for all the questions.. I thought maybe you have looked at some of this stuff already.

Bob

Bob,

I'm using an LA727 in mine, you use the flexplate that came with the Hemi but need to cut the ringgear off the flexplate and (may or may not need to) waller out one hole so the tc from the 904(727) will bolt on, I had to. I'd like for B&M to come out with a flexplate to mate the Hemi with a 904/727 and variants.

I saw the S&P fuel system they used on the Challenger but I didn't think they sold it as a kit when I looked into it. They used a custom built tank, external fuel pump, vette filter/reg (for return line) and sent only one line up front. I'd be concerned about pressure loss on a single line to the front but that may not be an issue. I chose to go with Don's design at FBO for my setup; a sumped baffled stock tank, external pump, -8 to the front, regulator at the fuel rail, then -6 back to the tank. You will need a fitting welded onto the fuel rail for AN line. AFAIK the fuel requirements are the same crate or takeout (58psi).

Don't worry about the questions, I have plenty myself and if I've found a problem or solution I'm more than happy to share, please do the same. MP as an info source leaves a lot to be desired.

I'll be putting mine in the vert in the next couple weeks (barring any work scheduling problems), need to change the kframe first since the vert was a slanty and the TTI mounts are for a 68-72 V8 kframe.

-Daty

This might help, but consider the source first.

Can you use a B body stock sending unit in an A body gas tank? If so, you could get the Hemi style sending unit for the gas tank that has a sending and return line provision. Then, use the Hemi fuel filter/canister that has a return line.

I have this on my Road Runner now. You could then put an external fuel pump back by the tank.

Keep in mind that this is mostly Cliff Clavin style theory.

Speaking of Cliff Claven, here's my modified sender:

It's not pretty, but it's in there. I gutted an early steel PCV valve for it's tidy 90* bend and 3/8" connection, drilled a hole in my new SS 3/8" sender, sandwiched in a piece of fuel hose liner from an EFI-rated hose to act as a gasket, and screwed it down tight with a castle nut from a tie rod end that had the same threads as the PCV valve. Should work OK, but I won't know for another month or so... still in the re-assembly phase.

FWIW, my fuel system is semi-returnless... my AFPR is in the engine compartment next to the original A/C heater control valve on the pass inner fender, and the return line is the OEM 5/16" steel fuel line. The supply line is all 3/8" aluminum line, with a filter before the lift pump that feeds the pressure pump. I'm running a surge tank instead of a baffled tank. The surge tank is actually a VW piece, with fittings that I feel are too small on the return side, so I'll be making my own tank with -6AN weld fittings after I get back running. Fingers crossed again...

Clair

Daty,
Thanks for the reply..

I didn't have a flexplate with my engine so I need to get one. A flexplate from B&M would be nice. I'm using their flexplate for my 360 in the Dart right now.
Do you have to have a modified fuel tank with an external pump?
I still need to speak with Don about the fuel system. I may call Street & Performance as well and see what they say. I have talked to them a few times before when I was looking for a Hemi engine. They seemed like real down-to-earth kind of guys. No bad attitudes or anything like that.
I'll need to change my K-frame also. The guy I bought my Dart from used a lot of parts from a '74 car. Luckily, I have an earlier K-frame that I had power-coated several years ago.

Bob

Brad,
The B-body Hemi sending unit and filter with return line sounds like it may work in some fashion. I guess the question is whether the sending unit will work in an A-body fuel tank.

I don't think a return line will be a big problem though. Usually return lines are plumbed into the filler tube. Cut a hole in the filler tube, thread the hole and screw in a nipple.

Bob

The tank I'm getting from Don is a new stock tank the he cuts open and installs a baffle and sump then puts it back together. I like it because it will bolt up with what I have instead of making custom straps or cutting the trunk floor out. The pump is external, which reminds me I need to call Don and get an update.

I was thinking of installing the kframe and motor/tranny from underneath but I'll probably install the kframe first then drop the motor from above. I'll leave the t-bars out (if I can) for clearance.

S&P may have a flexplate laying around leftover from hemis that got a 5 speed install.

I'm STILL waiting on TTI for the block-off plate, it'll be a week (like it was several weeks ago) when I talked with Sam earlier today.

-Daty

My forced induction EFI motor requires more pressure and volume than either of your new Hemis. The demands on my fuel system are going to be much higher.
I used a stock fuel pick up in a stock fuel tank. It was modified by adding a return port that sticks into the tank about 2 inches. The Vortech T-Rex fuel pump is mounted in line.
I have no problems with fueling the TT440. Everything works great.
I understand wanting a good quality fuel system but I think you guys are really taking steps that are more of a want than a need.

hey daty,

just dropped her in for the first time last night.
comming in from the top was fine - only issue I had was the bleeder screw from the tierod was in the way of my lift's leg. Charlie's oil pan from ohio is a Perfect fit! some issues so far without the exhaust manifolds on looks close on the pass side shock tower. have the power steering gear box in now seems I may have to swap it out with a manaul box. flywheel and bell housing were not on and dont look like Ill get it on after for its too tight- will re pull her out to mount the bell housing and stock exhaust to recheck the fit. the stock fan will go because at the best will be one inch or less to the radiator- will opt with the electric double fans.

another pic front view.

looks like I may have a hood clearance problem with the throttel body and my rallye hood. might have to go with a shaker hood. a big plus if I do but the down side is I will have to redo a paint match^@#*! I have the hood and knew better when I was painting the car at the time to shoot them both just in case.

aint that just like me thou...
so what's the difference, its only a few more hours added to the couple thousand I have now to make that happen!
if im not doing things on this car two or three times over with this sentimental 'BIT---CH'
she's acting as they do when ' on the rag '

440WB,
Can you ditch the OE fan clutch and use a shorter one? FWIW, 1" clear sounds great to me. Just don't hit anything...

On the hood... although a Shaker would be more appropriate, I bet a T/A hood would provide plenty of room. Might be easier to hook up a fresh air box, too.

Wishing I had these problems...

Clair

some good points clair

any idea about the fresh air box? any pics or info to who would stock or make them. at S&P they had a challenger last year with a custom made intake for the 5.7 after calling them mark says not now but maybe a few months they might make some more?

another thing about the throttle body is it may be sitting to far back for even a shaker hood? another measurement to make. also noticed that the oil filter has to change too.

I have to ask about you 'wishing you had these problems?'
are you refering to the hood thing?

The fresh air box in my mind is just something that would seal to the bottom of the hood, it doesn't have to be fancy. Once you sort out how to to filter the incoming air before it gets to the throttle body, constructing the box would be pretty straight-forward, I would think. For that matter, the throttle body doesn't have to STAY bolted up to the intake, it COULD be relocated with some form of adapter to some place more convenient if necessary. That would require some more complicated fabrication, but certainly do-able. There are all kinds of neat air fliter elements out there these days, from cone to flat round to square panel, all kinds of things to work with.

As for wishing I had these problems, it's the New Hemi problems I'm wishing I had. I'm just doing an EFI retrofit on my 340, and watching closely as my nearly-neighbor Daty deals with all the pain of the Hemi install. Fact is, I was looking VERY closely at installing a 4.7L OHC in my Valiant 4-5 years ago, and if I hadn't trusted some bad information I got about the bell housing bolt patterns, I might have done that rather than my 340. Upgrading to a Hemi after the 4.7 would have been pretty easy, I bet.

Clair

At home I have a photo that I will post tonight to give you an idea on what to use for a filter on a hood scoop. It is off of Ron Silvas Demon and when I seen it I said hey that is pretty simple but effective.
