Hey everyone I have a 418 stroker built by TSP and was wondering what kinda numbers you all think it would put down.
Car is a 98 Trans Am M6 with stock 10bolt.
Specs:
LS3 418
Prc 237 heads
235/242 cam w/ 112lsa
Kooks 1 7/8 headers
Kooks catted true dual exhaust

Any guesses?

what intake ? cam is on the small side but with it ironed out,i'd say 500-520 rwhp, 490-510 rwtq.

I knew I was leaving something out. Intake set up is Fast 102, 102 throttle body, 100mm maf, 104mm lid

Depends on the dyno my man

Regardless it should kick some *** on the street and track

Haha yeah that's what I figured. It's going to make for a fun DD haha

That's definitely a potent n/a combo for sure! Just don't get hung up on a certain dyno number. Regardless of what that dyno might say I'm sure it's a "true" 500 rwhp car at minimum

I think the above posts are close. I will say 510hp and 500tq.

Do you guys think I could go a little bigger on the cam size and still be streetable?

I think you are going to have a lot of power as is. What compression ratio are you going to run? What intake manifold are you going to run?

Intake set up is Fast 102/102. As far as CR I'm not sure. It wasnt included in my build sheet for some reason?

well what is your piston dish,head gasket thickness and cc of heads ? with enough compression, like 11:5 or so and a cam like say a 247/251 on a 113+3-5* advance ground in 540-550 shouldn't be hard to get. heck just look at my combo that at the time had a 90/90 and 1 3/4 headers. 538/486.

I'm pretty sure CR is 11.5:1 but I'm not too certain since the pistons arent on my build sheet. I had this engine built last year so its not really fresh on my mind. I did email tsp to see of they had my build on file so I can find out what pistons I have though.
