I have a 4 bolt main 350 that came out of a 91 silverado. im want edelbrock performer rpm aluminum heads. but they dont make them for the year of 350 i got. is it because of fuel injection? once i get the heads on im going to but a holly 4 barrel on it so i dont know if that would make a difference or not?

oh yeah and it needs to be edelbrock because im getting it 30% off at yearone.

 

any heads should fit that block. Might be referring to self aligning rockers or something ('91? shouldn't have it..?)
Perhaps the injection, so I wouldn't worry about it, pick the heads you want to use.

 

30% off year one? So youre paying everyone else's retail.

I am wondering if they do not have it because of the centerbolts heads/valvecovers. Isnt a huge selection of those normally. TrickFlow makes heads for it, and so does AFR (which is what I have.)

 

buy whatever heads you want and get a matching intake for them, the year of the engine block does not matter, just the intake bolt pattern of the heads must match the intake.

 

thanks. what kind of intake should i buy? my friend said he would sell me some alumium ones for 50 bucks but i dont know if they would fit.

 

holley street dominator p/n 300-36.

 

if you dont have to worry about emissions, go with vortec iron heads and any vortec intake and carburate that thing. with a 268h comp cam youll make around 400 horsepower. use at least a 650cfm carb...
