I built a 331 for a friend of mine and we arent quite done with the rest of the car, this is the setup anyone know a ballpark power output?

Trickflow R series intake
75mmtb
edelbrock vic jr heads 2.05in vlv 1.60ex 210cc intake runners and 76cc exaust port
comp cams stroker grind 579/579 615/615 with 1.7 rockers 236 248 dur
42lbs inj
76mm mass air
comp ratio 10.4:1
1 3/4 in shorty headers
2 1/2 in x-pipe
dynomax ultraflow mufflers

any educated guesses are appreciated, if you know of any similar combonations and power output please do tell! i know there is no sure fire way to know exept thru dyno which will be done after were done with the car! Car is a 93 lx notch.

Seems like a decent build. I've heard of similar builds going anywhere from 350-380 whp. Does it have to be EFI?

Venomantidote95

yes that is where the trickflow r series intake and the 42lbs injectors plays it`s role!

im not a guru by any means, i know whats on my car and how its going to work, the setup doesnt seem too bad, large head, high rpm flow intake, im guessing it will be a little lazy off the line, esp if its an auto and gearing is going to be a problem if stock, but i imagine from 3k it will move.

well we have a 3200rpm converter and 4.10 gears cant be a slouch out the whole, not asking about al that just round about numbers on the setup!

who knows, just b/c it makes 330-380rwhp, (the auto just kills hp too), it doesnt mean you are going to "fly", i would worry about ET more than dyno power. theres a guy, 302, gt40 junk, didnt make much more than 305 rwhp, he changed something it would have added a couple ponies, and mustered a 11.19 @ 115, thats an example of too much gear and not enough hp...

being an auto im gonna say between 313 rwhp and 18824736 rwhp....lol.

18 million hp, i wouldnt even want to ride in it, its either going to explode on launch or just warp into some other time zone, if not both lol

i hate our local forums cause of this same crap, noone can give a mature statement, i appreciate your input.

My guess would be around 450ish at the crank at around 6,700ish rpm maybe? Big cam, big heads, big intake. A 331 with that setup and a 3,200 stall with 4.10's should get down the track quite quickly though.
