Post your Hemi stroker Build - 01/31/15 03:32 AM

Looking for build up ideas for a 68 super stock engine. Car will be an automatic mostly street driven and run on 94 octane. I want to use a factory type cross ram.
Thanks

Well the last one was a 484 Hemi with 4.15 stroke and 4.310 JE pistons and 11.6:1 compression on pump gas with Indy 426-1 heads ported by me flowing 400cfm, and WP Iron block...In its hey day it made over +700hp, but I detuned the cam a bunch for more street use as it tended to eat parts....So I removed the .738 cam and pulled the efi off it, and went to a .590 cam and an SV1 carb and it made 660hp...Went a best of 10.74 thru the mufflers on pump gas

EFI and big cam....


Small cam and SV1....



My current build is an 11.25:1 all aluminum 605 Hemi with Indy alum block and Indy Hipo heads, aka Canfields, and it has a mild .685 mechanical cam and will have the injection back on it. Depending where the flow numbers on the heads fall, we should see +800-850hp out of this one...Purchased everything from BG Racing.

I'm in the process of my first hemi build. Muscle Motors is putting together a 605 Callis/Oliver bottom end, and I have yet to select the heads. I was leaning towards a single dominator as I already have some money invested in N2O plates for this flange.

I started a thread on here and yellow bullet. Several people have posted their combos (most are significantly above my HP goal).

I can tell you seeing people race a Hemi is rare, and seeing people race a Hemi on N2O is like seeing an albino deer.. They still do it, but after spending all that money, its not like killing a SBC with N20...Heck even getting the basic parts for a Hemi can be difficult let alone what your building.

Basically with your combo, I see a couple choices, the Indy Hipo, and Stage V....

I would suggest you buy and read Rich Nedbal's book on building Max Performance Hemi engines.

http://www.amazon.com/How-Build-Max-Performance-Hemi-Engines/dp/1613250746

Mine is a pump gas 572" World alum. block Stage V heads.

I didn't care for that book. I was expecting something like Andy Finkbeiner's How to Build Max-Performance Mopar Big-Blocks, but the Hemi book kind of fell short.

Mine will be at the track, but will likely without the bottle. My HP goals appear to be quite modest when compared to similar sized Hemi builds. At the rate I'm going I'll need a NHRA license and parachute without N2O. One of the MP or Indy crates probably would have been fine, but with the mixed reviews on this and other boards; I felt I could spend a little more and have a piece of mind. That some how turned into an aluminum 605.

Great info, thanks!!!

I'm a few hundred pounds lighter (3621 lb) with a iron wedge and factory K-member. I don't know how much I'll shed switching to Alterkation and this Hemi, but it looks like I'll be doing a chassis cert next year. Look for some chassis cert threads/questions from me after I get this thing back together.

I agree all the way. I read Andy's big block book first also. I did learn a few things and it was nice have some pictures. But the folks here have filled in most of the blanks.


I'm in the middle of building my Hemi. Its a 472. Stock iron heads, 10.5:1. Most parts came from ebay and Moparts so its been a pretty budget friendly build so far. I am in process of rethinking my cam choice and have several companies looking at specifying a cam for me.

Re: Post your Hemi stroker Build - 02/03/15 03:17 AM

I had Gary Stanton build mine. It's a world block 472. I stayed with standard bore and went with 4.125 stroke. This is a street motor that I just wanted a solid power plant that was a Hemi! They use Scat crank and rods. He also used Diamond pistons with 10.5 C/R. He used the new MP(Eddelbrock makes them if I'm correct) aluminum heads with 2.25 intake valves and 1.94 exhaust. I went with stock MP rocker gear. He put the biggest hydraulic flat tappet cam that comp grinds for him. I don't have the grind number handy, but it was a 108 LSA with around 580 lift and 249 duration @.050.. On top I have a street hemi 2-4 intake with 600 Eddy's. It dyno'd 583hp @6000 RPM. The cam should make power to 6500 RPM and since the Hemi's love RPM and hydraulic cams don't, we didn't pull any higher. The dyno pulls felt good with smooth power up to 6000. I wanted to be between 575-600 HP, and we seemed to achieve that. Gary seems to think we left some numbers on the table only pulling to 6K. All in all I'm okay with that.... Engine is going in my 70 Challenger with a Passon overdrive 4 speed, and a Dana with a 3.54 gear. So that'll be plenty of street pounding power for me!

Re: Post your Hemi stroker Build - 02/03/15 03:25 AM

I hesitate to post on a "race" forum but here goes. I have a early Siamese block (2000) Callies 4.5" crank, 4.375 bore, 10.75 comp with port matched MP aluminum heads. Cam is .246/.254 @ .050 .585 net lift on 112 separation, solid roller. Stage V intake with (2) Holly 750 carbs, TTI 2" headers. We dynoed the engine and it pulled 635 HP @ 5900 rpm. BUT when I got it home and installed in the car, it didng't feel right so I checked TDC with a piston stop and checked against the tab where the engine builder set the timing. Care to guess? it was retarded over 10 degrees! They dynoed it at 32 degrees? I put a vacume gauge on it, set the initial, welded up the advance slots etc. I am now running a TRUE 35 degrees total and it feels MUCH stronger!
Still runs great on 93 pump with vacume advance bringing the total to 44 degrees under light load with no detonation. Car weighs 4,175 empty, 3,000 stall with 3.54 gear and GV overdrive. Just a street car though. If I was going to race, I would have started 1,000 lb. lighter. Can't beat it though in summer with the top down!

My combo is built for street and pump gas as well. A bit milder than some here. I like building my own.
4.5 X 4.5 K1 crank and rods, CP 10.5 pistons, Stage V heads (CNC by MCH) comp solid roller by Dwayne Porter, about .670" lift and 270* 112 LSA mild lobe cam, Stage V rockers Indy intake. Just changed to Gen III 1050 Dominator from 1050 Race Demon 4150. No test results on the new carb swap. Milodon dual line pick up. Will be trying a cross ram RR intake eventually. HP is unknown.

i built mine, but the last thing i wanted to do was end up with an engine of mismatched components. there may be another time coming, but i figured i was only going to do this once. i spent time on the phone with tim banning at FHO, and we talked about exactly what i wanted from this engine. he then assembled the list of parts, including a cam that he designed, (herb (scatpk) also used this cam), and sent everything off to me.

i then shopped around for everything else, and it all came together nicely!

Re: Post your Hemi stroker Build - 02/04/15 03:38 AM

Have'nt seen any builds with the factory steel heads. Would there be that much loss over the other heads. Mine's not together yet but 4.31x4.5, older s/s roller, 13-1 comp, a little port work on the heads, hogan crossram 2- 3310s. Hope it will move my 64.

Re: Post your Hemi stroker Build - 02/04/15 03:32 PM

572" Hemi (4.5" bore x 4.5" stroke). Built it myself.
KB block, Callies crank, Oliver billet steel rods, 11:1 Diamond pistons.
Custom solid roller by Dwayne Porter...276°/284° at .050", .672"/.651" lift. Really mild lobes for street durability.
CNC ported MP aluminum heads by MCH. DLI roller rockers.
Ray Barton single 4500 intake w/ a Pro Systems 1200 cfm dominator.
2.25" primary, 4" collector TTI headers. 4" exhaust.
727 w/ 9" 5k stall, 4.10 Dana, Caltracs, 295-65 drag radials.
Pushed my 3850 lb. cuda to 9.54 at 140.4 mph, 1.320 sixty foot (footbraking). On pump 93 octane.
Should be somewhere in the neighborhood of 825 hp.

Now at over 3900 lbs., but w/ nitrous, I'm hoping to get an 8 sec timeslip this year. Went some 9.30s last year spinning the tires.

Re: Post your Hemi stroker Build - 02/04/15 03:48 PM

Tim Banning built 484 cuin. Moper block and heads. Original intake and exhaust manifolds. Very mild cam in the 500" range with full roller valve train. Edelbrock carbs .
I saw the build sheet on it a few years back and if I remember right, it makes just over 500hp and I think just under 600 ft lbs of torque.

In a 1970 Cuda, John Cope built 727, 3200 stall conv, 3.54 Dana. Running 295-50-15 tires. It will haze the tires at will at anything under about 50 mph without a whole lot of effort by your right foot.

Car is a blast to drive,,especially with the Vintage Air a/c system.

Here's mine...........



The big box under the bench is a new World block. The 2 white boxes are MP/Edelbrock heads ported and assembled by MCH. And I have a Barton intake, DLI rockers, Direct Connection valve covers and assorted other goodies.

Just need to put the coins together for the reciprocating assembly and cam, lifters, etc. Probably something like 540" with a 250*ish solid roller cam for street/strip. Didn't get it done last year, maybe 2015 is the year?

Hughes is claiming 447 on their "Prepped Edelbrocks." I've been busy at work, but will be calling them to see how the Eddy heads compare the Indy's that they've had on the same flow bench.

http://www.hughesengines.com/TechArticles/1headflowchartscomparisons.php#EdHemi

A pic I created comparing Stage V and Hughes-Edelbrock:
Posted By: Hemi Allstate

Re: Post your Hemi stroker Build - 02/06/15 11:03 PM

The Stage V heads in that example do not have the same size intake valves as the Edelbrocks. They are smaller, (2.25") and it does make a difference.
So, not an accurate comparison in IMHO.
