349 CI on the cheap
Interesting engine math on this one
Rod ratio: 1.84
Stroke to bore ratio: 91%
Rod angle: 16.99 Degree's
Piston speed @ 6500 rpm: 3878 FPM
My cam quest program shows massive gobs of torque,with a SMALL cam!
Comp 275DEH shows highest average tq at 162ft/lb, peak 415ft/lb and 398 h.p. Several other small cams show higher peak #s. This is with a pocket ported 360 head and big 2.02 intake valves,9.6:1 compression using an .040 over piston with 1.658 ch. Magnum heads will boost compression around 10:1.
BJR,at what point (how much lift can i use) will I run into piston/valve clearance problems using an LC371P piston with no valve reliefs? Got lucky and found a set! Looks like they have a slightly dished top. The pistons have a recessed head of .040” deep X 3.000” dia.
I have also come up with some possible pistons for this engine combo
Silvolite 1278. Think this one was mentioned already..
Badger P287
AE Clevite 2241930
What can you tell us about these pistons?
My approach will be a bit different from yours. Im looking to build as much low end tq as possible using a pump gas cr and cam. I want a stump puller for my heavy M body!
