running 180cc,alum,202,160
flattops but 308 ring.

here is rundown, 76 stinkray 4th one ive built, never had prob swapping out gears so i could run over 500 lift on cam well i just opened up my wallet and a bat flew out.

car is stripped down in garage for this winters project...once again a glutten for punishment..or a devorce, ive done what i always do to vettes and that is heater/ac delete and anything else that weighs but the rear end is brand new with same 308 gear so i'll keep it for now and that is what brings me here

with this 308 gear what cam should i run and stall so i wont fall on my face? i know getting over 470 lift i need to upgrade my TC im not used to this gear im used to 373's,390,411

keeping 350 trans in it for now, my intake and carb is no biggie i got a few and will always rejet

need input and what worked best for some of you thanks alot

,ike

I think you may find it a little difficult to get any really snappy power out of a 3.08 gear regardless of the cam. A relatively small cam will help though. According to some of the aftermarket head compaines, a 180 runner head should make power around idle to ~5500 RPM in a 350. Based on that, a cam that should perform in same range would be XE262H (218 224 @.050 .462 .469 lift rated for 1300 to 5600 RPM) You could go a little bigger or a little smaller and still have a nicely matched motor. If you plan on having the 3.08 gears in there for a while, I would probably recommend something like the XE256H (212 218 @.050 .447 .454 lift 1000-5200 RPM). Calling Comp would also probably be a good idea to see what they say.

I agree

I have a 70 chevelle with the same setup (for the record, this set up is only temporary)
stock 350
brodix IK180 2.02/1.6 (64cc)
comp cams 4X4 XE262H
th350 (1800 stall)
stock 2.72 gears W/26 inch tires

it has quite reasonable power down low and will leave some nice rubber on the road considering the poor gearing... really starts moving around 3500 rpm.

like firestone said... better gears
