mods are tsp prc 215 heads trq v3 ls6 intake and tb slp undedrive pulley
36 lb injectors air lid yella rockers tsp headers 3 ofy borla cat back

i made 440 rwhp 427 tqr
dyno graph is on its way the dyno shop's printer was broken

 

Assuming its a 346 the Tq is a little suspect...what type of dyno?

 

that is good numbers, that shows you dont have to have big heads and big cam to make big power.

 

the cam specs are 231/234 .643"/.598" 111 LSA

 

Nothing suspicious on a high compression with that grind.
One of my cams (same range) makes 465/428 on 346. 400 lbs by 3500 rpm. It can be done.

 

umm the PRC 215 heads run over 2 grand. thats AFR/TFS money, so idk what you consider "big", maybe ETs?


unless you were thinking these are the PRC LS6 or 5.3 heads, i could understand that misunderstanding. the 215's are an aftermarket casting.

 

Those numbers are definitely possible, we've seen over 430lb ft numerous times with the new PRC 215 heads. The torquer 3 camshaft works very well with the PRC 215 heads at 62cc.

Enjoy the combo & let us know if you ever want a ported Fast intake combo to push that thing up even more!!
