Hey all,
Sorry if this isn't the correct area to post this, as this is more engine specific than it is vehicle specific. though you could say that i plan on dropping this into my 97' fox and that i want some help on the motor for it. otherwise, i couldn't for the life of me find an engine specific forum here.
so anyway. I've got a 74' 351w that I'm wanting to stroke to a 408. I'm going with a 4" RPM forged crank, 6.250" forged Eagle H rods, and forged JE Twisted dome 1.230 Pistions with a -19cc dome. Zero Decked, overbore to 4.030.
750-800 cfm Carb, .037 gasket, Edelbrock Vic Jr heads with a 60cc chamber, and a Edelbrock Super Victor Intake. (The rest shouldn't matter for my combustion ration as of right now, lets assume the rest is pretty neutral). JE is claiming that my setup would get me 10.7 cr at a 58cc head, so with a 60 i imagine my cr would be around 10.5 give or take.
I don't think I'm using the online calculators correct because I'm getting an estimate of like 18.5 cr (kaboom). so i wanted an opinion from some guys that i figure have some experience with this.
Hows my setup looking so far (excluding the fact i don't have a cam chosen, but I'm looking at one to get me to about 6500rpm.) I'm trying to keep my CR at mid to low 10's on 93 pump fuel and decided to go NA instead of having a power adder.
Thanks in advance.
