The engine in my dart is a 1975 440:
.030 over
Trw L2355 six pack pistons
MP 284/484 cam installed 2 or 4 degrees advanced. (cant remember, been a while)
Bone stock 452 heads
Compression is 9.4:1
Stock intake
Demon sizzler thermoquad
Hooker 1 7/8 fenderwell headers
3000 stall convertor.
Thinking of getting some heads. I would not be able to afford any porting to the new heads so they need to be good flowing right out of the box compared to my stock 452 heads. SO, if i got a set of new edelbrock heads or something similar, what kind of HP and torque gains could i expect? They say the edelbrocks and all these other heads right out of the box outflow the stock heads ported to the max...Is that true?
