Not gonna be street driven. OK, where will it be driven?
Can't intelligently choose a cam without knowing the static compression ratio.
Factory stall won't take much cam and "not much cam" won't take much static compression ratio.
Stop looking at cams until you know how to figure SCR.
You'll need:
1. cylinder volume in cc's
2. chamber volume in cc's
3. piston crown volume in cc's
4. piston deck height volume in cc's
5. head gasket volume in cc's
Is this a roller cam block?

heads 76cc combustion..... 170ccintake runners...felpro 1003 head gasket 9.1cc....yes its roller block....has factory flat top pistons...think compression will be close to 8.81-9.5......actually gonna be in a derby car....gonna also be runnig a 513 gear
