Big Torque 499' Stroker with stock manifolds

[Turboomni]

Intersting profile...Mind if I ask what it cost to have a custom grind made? Second question, how do you think this cam would react if I eventually switched to headers from HP's?

I would refer you for all questions to Dwayne Porter for answers @PRHeads. I am rather cam illiterate and had been recommended by many [including FAST type racing guys] to go to Mr Porter and explain everything I wanted and the car it will go in.

Dollar for dollar a good set of aftermarket heads, cam, and headers on your existing engine will make more power than a stroker with 906 and manifolds.

I would tend to agree but in my situation I wanted a stock look of HP manifolds and lots of torque at lower rpms to get my 4000+ lbs of car moving without having to rev it and only run pump gas. Also I wanted to keep 3.23 rear end ratio so I can go down the highway. I cannot speak to the OP's situation as his car as well as yours in your Avatar are much lighter than my Fury and I'm sure you both may have very different objectives in your performance expectations than I. If I had a lighter car that I wanted more race oriented, I am sure I would have very well taken a slightly or much different approach.

You all should see my Summit Racing shopping cart, its full of a bunch of different cams, lifters, pistons, heads, headers. I need to start narrowing it down.

I could easily be diagnosed as a BiPolar engine builder or something.

 

[Turboomni]

I'm sure many here would be interested what you are considering.

Option 1:
499" 9.0 to 1'ish with dished pistons (4.375)
4.15 MP Forged crank
K1 Technologies billet H Beams
Current 906 Heads with 2.14/1.81 (88cc)
Hydraulic Roller Custom Cam similar to above referenced with 113* LSA ($900 min)
HP Manifolds

Option 2:
499" 10.2 to 1'ish with same dished pistons (4.375)
4.15 MP Forged crank
K1 Technologies billet H Beams
Edelbrock RPM's 75 CC ($1599)
Comp Cam XE282S SL with EDM lifters (not 100% sure on cam yet) ($400)
Comp Pro Magnum Shaft 1.5 Roller Rockers ($699)
Doug's Headers D452 ($725)
Head Studs ($184)
Edit: Forgot I'll need push rods too

Extra Cost for option 2 = $2700

My guess is 100 horsepower / 120 ft/lbs difference between the two options.

 

[Turboomni]

My uneducated guess would be maybe yes on the HP difference but I don't think the torque will be that big a difference but wtf do I know. Target torque is 600 starting around 3000 on my engine.

 

[Turboomni]

I would have thought more would chime in on what you were thinking of doing.

Go to Muscle motors and look at some of their crate engines to get some ideas. the 472 has always been a great engine combo.

 

[Superbeemike]

I would have thought more would chime in on what you were thinking of doing.

I was hoping there were more exaples of the iron head recipe being used.

 

[Turboomni]

Yes that would be very interesting to read about. Many ways to skin a cat as they say.

Could always stay stock stroke if you want to stay as close to your budget as possible.

Icon pistons at zero deck.
Have your 906 heads milled to get down to 80cc
Small solid roller cam
New rods
Hp manifolds
Rockers and pushrods

And in my opinion staying with a flat tappet cam would probably be just fine as you won’t use the full potential of a roller cam anyways sticking with manifolds and iron heads.

Even with the right flat tappet cam, sticking with what I wrote above, I would guess 450-500 horsepower.

I spoke again to the owner of the New Yorker video I posted here . He said his best time was 12.40 etc with Log Manifolds not HP as I stated, stock diameter exhaust and mufflers . He then went to TTI headers and TTI complete exhaust with 3 inch Dynomax mufflers and the ET went down to 12.20 or 2 tenths so far. Interesting as I thought it would be more.

 

[BLK 68 R/T]

12.20 in a big *** car like that is not to shabby in my opinion.

 

[Turboomni]

I agree it is very impressive. Especially on pump gas. If I can have my Fury a solid mid to high 12's car on pump gas it will be mission accomplished.

The problem with nailing down an answer is you are unclear on what your performance goal is and its priority to cost.

Good news, because you have been to the strip you have some thoughts on how fast you might want to go. Additional helpful info would be race weight, and some track met. data.

If going 12.50 - 12.75 sounds good to you (i.e. 150 HP increase ) Consider Option 2 with the following changes. Keep the manifolds, Mancini 1.6 rockers, 282/290 XE lobes on a 114 lsa. You'll save $800.

I have a 500” stroker in my Dayton stock eddy heads 10.4 compression stock manifoldS hughes cam around 545 lift 3:55 gears. Runs great on 91 gas. 750 Holley on RPM manifold
Runs very strong till around 5700RPM 2 1/2 TTI Exhaust. Very street able and will Smoke the tires with ease

I should try to clearify a bit here....

I would love to make 500-550 hp. My wifes new scat pack makes 485 and I gotta one up her, right?. I'm looking to spend $3000 but can budget more if I need too. I have some 1/4 mile data only because I was there for the Roadkill event last January, not because I'm a regular. Drag racing isn't really my passion so I'm not trying to achieve optimum results there as I do a lot of distance driving and road course use. Not saying I won't go again, just not as important. If I had to guess, I'd like to be in the 12's so I can beat the new Challenger. I have really started to love road racing and high performance driving events. Big torque is really what I'm after so I can get the car up and out of the corners while at the track. I haven't weighed the car but my guess is the neighborhood of 3800lbs.

I do appreciate the responses from everyone here. Thanks

OK, the 500 combo l posted earlier in my 3400 lb cuda ran a best of 11.50 at 120 mph through full 2 1/2 inch exhaust with 3.55 gears on drag radials. The torque was awesome on the street, but I think you would have to be very careful coming out of corners if you were on a road course.

Other than the headers, I think thats the Iron Combo thats closest to my option 1. Maybe with manifolds it will be around 500hp. You're right about the torque at the track but I prefer to have it over high rpm horsepower.

 

[69 GTX]

And probably within your budget too.
