Is there anyway you can install 307 SBC pistons?
307 pistons will be closer to the deck.
IIRC, Felpro HG are .038 compressed.
I believe I have some NOS HG that are thinner than .038 more like .035 ish?
Silver in color.
They are round bore, no valve relief notches, I forgot the brand name.
I think I bought them from Clifford years ago?
With .098" that is not considered any quench & could actually cause the engine to detonate from being down the hole so much.
With the low deck blocks being weak in the driver side fwd head bolt area & tends to crack with a stock thickess block, shaving it .057" will make it more weaker.
If it is a stock engine, you could shave the block, run a head stud in that corner & run less final torque, you could probably get away with it, but it's up to you.
I would get the correct height pistons, or even pistons that come out of the block some & shave the pistons down before shaving the block that much.
If they are available, the factory steel shim gaskets are .020"ish?
I might be thinking of the older 194 6 cyl head gaskets.
Anyone?
