I scored like a 20,000 mile engine out of a motorhome 800 bucks like new... ported with 30 hours of finess and pain cut my 3 angle valve seats on the peanut port heads.. the bottom end was already decked like ten, 0.020 head gasket yielding like8.1:1 instead of 7.9:1.. took a lunati 60202, had it custom ground on a 108 LSA to get just under 7.4 DCR , Gets 15in of vacuum with 16degrees initial and a q-jet at say 700 rpm .. cheap regular street sized headers... There is your 500+ ft lbs of torque... here is a similar with junk peanut heads( unported) same cam on the 112 LSA on 8.8:1 compression dynoed:
