My SBC 388 let go a few weekends ago and damaged my favorite little Erson solid flat tappet cam I had in it. Money is tight right now and trying to get the motor back in service as soon as I can I found a cheapo cam with a close lift and duration that I had. It's a 257/257 @ .050 .553/.561 lift on a 102LS, my Erson was similar to this but was on a 106. Will the 102 vs 106 LS hurt performance?
The motor is a 388 with pro action 210cc aluminum heads, super victor intake, E85 fuel, 12.75 compression, 3000 pound car, 5500 stall, 4.56 gears, 1/8th mile car.
Thanks,
Kevin

I think so but it might surprise you,, I would try it if you have it as I have found there are many times these engine do not read the same magazines we do,,
Watch the p/v clearance with the tight LSA

Are you sure the LSA is 102, or is the Intake Centerline 102?
Not too many cams are ground on 102 LSA.

That 102 may be a little too tight in my opinion
If you have it try it but back the timing back a few degree as that cam should make more cylinder pressure than the old one and it may or may not push you into detonation
I see you have E85 so there should be no issues but............ Be carefull and try it

Why would you assume cylinder pressure will be higher with this cam,vs his old one?trmnatr wrote: If you have it try it but back the timing back a few degree as that cam should make more cylinder pressure than the old one and it may or may not push you into detonation
Let me guess dynamic compression??
