This is a little weird guys because I don’t remember every detail.
About 2017 I bought an engine Frank (All Pontiac) was listing for a friend who had passed. I sold the heads to lower the compression and installed 87cc heads.
It’s a 455 filled to the soft plugs. Steel 4 bolt straight main caps with arp studs. Lifter valley brace
Scat 4.21 forged crank
6.8 Callies Comp Star h-beam rods
CP gas ported pistons with a slight dome.
Moroso oil pan.
Comp solid roller cam .750 lift? Ground at 110? .270@.050? Not exact but close.

With 335 cfm (87cc) Edlebrocks this engine made 735hp. It ran 6.40s in a 3400lb car at 3200 feet.

I’m keeping the heads for a future blown project so just the short block is for sale.
$3500 plus shipping.

How much dome? What was compression with the 87cc heads?

Pretty sure it was just over 11:1

I’ve changed my mind on keeping the heads. They’re 335cfm (87cc) Edlebrocks with T&D 1.65 shaft rockers. All this engine needs is an intake and carb.
$7,000.
