IMO 300hp would be really pushing it and retain some drive ability. If I was trying to keep the truck true to form I would give it a good rebuild and make a Power Pack out of it, those parts are easy to find and cheap.
Thanks z28, I really appreciate your reply.
Can you give me some more information on those "power pack heads"
do they give the motor higher compression--higher flow runners?. I went to get some numbers off the heads that came off of the motor the only numbers at all on the head was "550" on the bottom, i also noticed the heads don't have any accessory bolt holes on the end of the heads, if that helps.
I also have a summit-racing cam to go in the motor... 224 duration and 0.465 lift and a 114 degree lsa is that going to be to much cam for this smaller motor? once again i bought this cam when i thought it was a 327.
Sorry for all the questions.
