Default How much power will my 302 make?

Well I'm currently building a N/A 302 to beat cammed LS1's or 150 shot bolt on LS1s. The combo is pretty mild. Some Trickflow TW heads, a Trickflow cam, and the Trickflow Box R intake. What do you guys think it will make/run all motor?

I'm hoping it will make over 400rwhp and maybe with the right gears run around high 10's low 11's.

302ci is only 225bhp, duh.




I wouldn't expect more than 350rwhp to be honest with stock cubes. What are the specs of the cam?

The cam is something a guy at Trickflow and I came up with. Its a hydr roller so nothing big. I gotta drive this car around daily.

400rwhp sounds tough on a 302.

I agree, this is what I'm hoping for though.

With a hydro roller I would say no more than 345-350rwhp.
A friend of mine has a Trickflow heads and intake but an E cam in his 306 and makes right at 320rwhp, but I'd imagine your trickflow cam has a little more "oomph" than his E303.

Bore your **** out.

Coming from the 5.0 world, i would honestly be surprised if you hit 400rwhp. Good luck though.

It might not make 400rwhp because of the T56. I'm not much of a dyno queen anyways. However I would like it to be somewhere around 120+mph in the 1/4th all motor. 11.50's on street tires and maybe 10.90's on slicks.

With a 331, 400rwhp is definitely possible with cleaned up heads a nice intake and custom cam.

Should be a real fun street car.

Ah look it's one of those cute little baby motors. Seriously it sounds like it will be a nice combo.

Ya know you're missing 2 valves.

Seriously, just curious why you didn't go with some AFR's?

Not to start a war but I've had both heads and I feel Trickflow is much better than AFR both in flow numbers (obviously) and how fast they make something.

I can't wait to get this motor together and throw some gears behind it. I don't think its going to work with my current 3.27 gears.

Best of luck with the new combo! I can't wait to find out what it makes!

Out of curiousity, what does your car weigh amd what are you thinking about for a rear gear?
