Can I please get some help with a street build 383.
Bore-4.280
Rod-3.375
Piston-L2315F
The short is together with a flat top piston and it’s .008th in the hole.
Cam is an MP 272 adv & .455 lift & 112 lobe
915 Heads are slightly ported they flow 233 @ 500.
Db4p slightly ported single plane intake
Going to run stock manifolds.
915 Heads are at 83cc after valve job.
I was planning on using Felpro .039 head gasket 4.50 bore
What is a good compression range for this combo? Not sure if I should leave the heads at 83 or cut them.
Street car, 4 spd 3:91 gear
