I've built several 302's and a couple 347's but I'm looking to step it up. Starting with a 351w as a base what could be the best setup to reach the goal of 400-450rwhp. (Dynojet/manual trans)

A few Caveats though:
Daily Driven
No Radical Cam and must be HVAC capable and standard breaking system
No compression higher than 10.5:1 for the use of premium pump gas

Give me suggestions on stroker kits, heads, cam profiles or custom cam maker

looking at a 750 or 850 choked carb built by me or the old man at SoCal Speed shop.

Links and real experience helpful

If you have any setups like this lets see what you got. I like pretty pictures.

I can't believe there aren't more old school fast cars on here.

Call up the Venom351 with the 1994 cobra with the 1995 cobra R drivetrain, I'm sure he can help out. Also, I'd go with Fuel Injection, Carb's are overplayed, I like have a cam'd car that is fuel injected, confuses all the older muscle car guys in my city ;).

One idea, use a 418 assembly from coast high. You dont have to rev the crap out of it, which i think would be ideal for a daily driver. I know paul had a 418 at one point. Hopfully he will step in here. But I would have to say 408 is probably the more common option. But then again saying you have a 427 is would be cool too. Sorry for helping so little. lol

Its probably going to be a 351/427 stroker. I will never put a big block in one of my cars. If I want BB power, I'll go forced induction. Oh wait, I've done that. LOL I just can't believe there isn't more people on here with power like this.

i dont see the point of going through the trouble of building a 450-500 rwhp 351 when it would be cheaper to build a 8.2" based motor that would run circles around that 9.5" motor.

if you think a 8.2" motor with a power adder = the same power as a big block then you are mistaken. a junk headed 385 based motor can make 600-700 for probably less then 5-7k. To build a 8.2 or 9.5 to do that your looking at close to 15 if you want it to live more then 1 pass.

I believe Paul's was a 422.

I've had a 418, which is now a 422 - with the only difference being a .030" overbore vs .040"


I wouldn't go carbureted, but that's my own personal bias. I think big Windsors make great naturally aspirated, reliable streetcar motors. I can't give much advice on carbureted combinations, since I have little experience with them.

My 422 runs an unnecessarily strong and expensive rotating assembly, high-priced and unnecessary rings, bearings, and gaskets, and a huge set of badass heads. I got my cam and valvetrain stuff from Ed Curtis, and topped it off with a TFS-R injected intake, 90mm throttle body, and 36# injectors. However, I never got numbers from it, and it sits in my garage now since I've sold the car. Wanna buy it? :tongue3:

Unnecessary weight from a big block and completely different animal for DD. If you've ever driven a BB car you'll know what I mean. I'm not making 7-800hp, I'm make 400-450hp and the 351 is best of everything.

Fuel injection is cool and all but in a lot of circumstances carbs still make more peak Hp than MPFI. I do have plans to use a FAST EZ-EFI but there's no telling when that'll happen.

PAUL, I thought you had an old SVO or Capri? ...Or something?

i've driven plenty of BB cars and unless you plan on taking the car to a road course the additional weight is not a factor.

give me a instance on where a carb will make more peak power then a fuel injection setup and why...

at 450 hp a 351 is not better then a 302 motor, hell since you like the weight argument the 351 will weigh more then the 302 based motor :)

Carbs don't make any more power than EFI. Airflow is airflow - the engine doesn't know any better.

No, my best friend has an old Capri, but I work on it with him and powdercoated the whole motor which is why you've probably seen pics.

Im with paul as far as the EFI/Carb thing. Go EFI.

If you want 400-450 RWHP stroke it to a 408 there are many places to get good stroker kits, DSS/CHP/Ford Strokers/ RNH to name a few. I would consult with one of them for which stroker kit would best suit your goals.

As far as H/C/I providing you dont go w/ the crappy carb (Im biased) I would go with nothing smaller then an TrickFlow/AFR 205cc head, Long tubes, and as far as a cam I would either contact Jay Allen from Cam Innovations or Ed Curtis from Flowtech Induction for a custom cam. Both are good at what they do the driveability on my 351 w/ a cam from Ed Curtis is very nice. Im currently making 400 at the engine. My compression ratio and need for probably bigger heads and need LT's is holding me back.

The car will race SCCA. (Although I'm going to be outclassed.)


There's a great debate over F/I vs Carb for peak power and I've worked with both and carbs have almost always made more peak hp. Now, we're not talking more than 10-15hp so don't get all twitterpated. Carbs are much easier to deal with and tune provided you have a good one. I told myself many years ago I wasn't going to build another Carb'd car but first things first. If I can drive my car with a 400$ carb and then convert later that's what I'm going to do.

Here's the EFI I'll be going with when it does happen. I've already dealt with Accel & Edlebrocks MPFI conversion kits and I hated them.
