the 440-1's are a max wedge port and I dont want to go that route for several reasons, no max wedge intake manifolds that fit under my hood, and wont -1s move the power up into the upper rpm's I I try to shift by 6/62k rpm.

from what I have figured the chamber on the Indy S/R will give me 11.2/1 compression with a .039" gasket. if I went to a thicker gasket it would be less, but Im fine with 11.2/1
The thing I like best about the /R is the room to grow in the future.




INDY Max Wedge 2D intake will fit under a stock B body hood even on a tall deck & will support over 700 HP. (they flow mid 350's out of box) I ran one on my '68 Road Runner with stock flat air grabber hood, 750 Holley & 2" air fliter, no drop base.

Remember anything other than RPM's, or EZ's will require special headers.... (raised ports (SR/-1 etc)
