pics and set up your running ? mopar are no car! p.s. 1/4 and 1/8 mile times

364ci W5. Haven't made it to the track yet and will be converting to 437ci soon.

My 422 W5 combo went a best of 6.15 on alcohol at around 3200 before I started spaying it. Then started finding the week link regularly. Went 5.66 with 250 shot.

1972 challenger 9.08 @ 146 at atco.
Engine built by G&S Performance. Heads ported by Ryan J.

nice #'s barry!

My old 422ci cement filled alky injected combo went 9.08 @ 149 with a burned up powerglide.

Where did you get the intake? If you still have it would you be interested in selling it?

The mopar intake is Junk

Get yourself a INDY intake

if i got a indy would i have to go to a 950 carb???

My combo.. no pics on my phone though.
3100lb 11.5 tire, 69 dart.
ladder bar, 727 trans
408cu.R block, W5s injected on alky
roller cam...
So far 6.13@113.05 1/8th
9.63@139.57.
If I can ever get it to 60 decent it will run consistent 50s easy enough. Only has went 1.36 and usually 1.37. 60ft. Just spins horribly at the hit. And if it does hook initially it will unload when the tires touch back down. This is also with no hood as the injectors are to close to the bottom of the hemi scoop.

Yes a 950 or 1000 4150 carb

would be good.

Your short block is OK at best a stock block and stock 360 cast crank.

You can make 600 HP with W5's and a INDY intake easy. That is not good for a stock block and cast crank.

I would keep your RPM's 6500 or less

We've gone a best of 9.87 @ 138mph. Changed converter and pistons and I think we've only seen 135mph out of it this past season. The "looser" 8" converter has netted us much more consistent 60ft times and running low 10's keeps us legal. We're running an Indy intake topped with a 1050 dominator. CNC ported W5's by Ryan. Probe pistons, eagle rods/crank. Conservative roller cam and aftermarket main caps. We run exhaust on the car and it sounds like a wuss idling through the pits......just the way we like it. We had to tear the engine down after 50 passes due to a porous head. At that time we discovered that a number of the comp cam roller lifters had cracked, thus the early overhaul. We're currently running lifters from Brian at IMM Machine. The engine was happy all summer and we may throw the 9" converter back in next spring to play with it......or our 904 trans/9" set up.

Good luck with that cast crank!!

Mine has gone a 5.93 @ 114 2750# 904,indy intake, 408" 360 block,scat rot.ass.diamond flat tops 12.5 CR, pro sys sv-1,mild crane roller.

W5s here, .020 over MP short block, soon to be replaced with a 408 and a .700 net lift roller with 2.08 valves.

What cam did you use?
currently have a comp 20-717-9

Shady Dell built pump gas 439", small chamber ported w5's, 10.7-1, bullet solid roller 272/276 @ .725, R3 siamese, Howards ultimate rods, K1 crank, Diamond pistons, TTI's, M1 intake (temporary) with Indy intake, and 1050 Dominator to go on. Will likely see a vacuum pump in spring. 660 HP at the moment- only to go higher...
No times yet- should be a mid-low 10 sec car with traction. All I know is with E70-14's on it's a handful, still lays rubber @ 80+ mph thru 3'rd gear and sounds sweet @ 7500.
GOOD STUFF!

what cam should i run ?????? roller cam or flat ?? what lift ??? what compression ? whats the highest rpm with what im running ??

I have a set. The combo they sit on is a wooden shelf. Haven't gotten around using them yet.

-Kenny

Been looking for a set so I can join your club!

I had a few sets of the early W2's (back in like 78-or 9)...and I WISHED they were aluminum...does that get me honorary mention?

What are your intentions with this thing- street/strip or drag only? pump gas or race gas?
Either way I wouldn't be using that cast crank - how many times do you want to build it?
The large plenum M1 is not the hot ticket for 360 cubes and as mentioned a 950 would be a better choice.
If your wanting max power there can only be 1 choice- solid roller- how high do you want to spin it?

i would like to spin it to at least 7300 im thinking of a scat crank ? so u think the profrom 750 is too small??? plus i would like to get the most compression i can get out of the flat tops. it would be mostly used on the strip but car shows here and there ps race gas

Yes I think the 750 is too small...it will work but you'll be shorting yourself on power. Look at the post of my buildup- Ryan dyno'd mine with a 950 and 2 1050's and found 20 hp difference. Now I am temporarily running my old 825 Demon and it runs GREAT but is it down on power compared to what it should be? OH YEA!
Call the pro's on this board when your ready for a cam- you could get 50 different answers here and they all might be fine but you've got to pick somebody for that 1.

Even our somewhat mild iron MP headed 360 liked the 960 BG carb we threw on it. That combo set a best of 10.91/92's. One thing I'm not overly comfortable with (on the W5) is the stock block we had access to. We just plain ran out of funds for a race block so did the best with what we had. Our 340 block is filled and does have aftermarket steel caps (two bolt). We're hoping it lasts. we also left some hp on the table in the cam dept as we didn't want a high maint valve spring eater.

i wish i had more cash !! lololol you guys wouldnt beleave what i payed for all that stuff i found good deals on ebay and at the spring fling !!!i got all my w5 stuff complete 4 less then 2000 all band new ! ? heads rocker /shafts hold down intake value covers where 120 headers 275.00 oil pan was 200 i will goo with a scat crank but cant buy a race block! how far can i spin that scat crank in a stock block ??? plus i guess i need a 950 carb now !!! wow ! but all in all its not a bad build !

Yeah just getting a set of heads for free can be a death sentence for your bank account. By the time you port them, and build the rest of the package around them so you can take advantage of how they work, it can get a little expensive. If I remember correctly we have about 9k into our build....and that started with a set of $800 used heads that were on an ARCA car out of michigan. Not a huge amount in this arena, but pretty good for our standards.

ya funny ! i was just going to buy some eddy heads a cam and be done with it !!!!!!!!!1lololol then i saw the w5s lolol i wouldve been done buy now! lolol

DI'm still running my 396 W-5 engine, after eight years she still runs 9.80's @ 138 went 5.70's last weekend on 150 shot and 275's

I will have a pair for sale soon along with an intake, they are the " good" ones with the blue plug. They have never been used and come with valves.

I have a set off my car I'd like to sell. Complete with valves, springs, sheetmetal tunnel ram, smith brothers pushrods, Harland Sharp 1.6 rockers. Only 40 passes on everything since new! I split the stock block in half and went to a race block and W9s. Car went 9.50s @ 2900lbs N/A 360 cubic inches. PM me if you are interested.

question ! i live in cal. who ported your heads ?????? in wanted to send them to shady dell's but is there some one closer ?? who did your ???

...our 5's went from Michigan to Arizona, to PA, to South Dakota, to PA, and back to SoDak. Should have got frequent flyer miles for them. Thanks again for a great set of heads Ryan. My dad is having a ball with that engine!
