Those flow numbers are with 1.94" intake and 1.625" exhaust valves at 28", easily 500+ hp with good parts and quality machining, especially with the combustion chamber designed the way it was. Those heads were decades ahead of their time, SB2 heads and most Nascar heads were copied from them in...

On the top front driver's side of the block there should be assembly date numbers stamped near the top of the deck near where the head sits on it. They will tell when and where it was assembled, what number engine assembled that day.

Can you please post a pic of vin numbers stamped on the machined pad on the passenger side of the main case?

NHRA class rules for superstock dictate the as delivered from the factory accepted CCs for cylinder heads. They fill the bottom of the ports to be able to raise and re-shape them for better line of site and airflow potential. It's been proven many, many times that improving the line of site and...

Can you please post a picture of the vin numbers stamped on the top rear driver's side of the block near where the transmission bolts on?

4" bore, 3" stroke 728 hp @ 9400 rpm. older X block without the extra head bolts, single 850 carb, wet sump oiling system.

The engine was originally designed in the 1990s for that rpm range based on what was standard practices at that time. 372 cubic inches, splayed 4-bolt mains added after cap walk was found during freshening, tubed lifter galley, W2 heads, Holley Pro dominator tunnel ram, two 750 Holleys, long...

Each setup cost somewhere north of $7,000+ each, probably $10,000+ each..

Was the intake actually bolted onto the heads or just the gasket set on it with the bolts in it to line it up? Could be the gasket bolt holes are off and the actual ports line up when bolted to the heads. Could also be the intake bolt holes are off and need opened up to line the ports up.

Phantasm, made in1979 and the sequels are great car themed scary movies, the original one is probably the scariest car movie ever.

I run PAC 1355 springs on the intake valves. New intake springs are installed @2.100" and have 450# spring pressure at that installed height. 780# spring rate and 1.130" coil bind. 1200# @ 1.175". They lose roughly 50# after break in. The collapsed spring has 295# at that installed height. The...

Did the OP find the root cause of his problem? I'm betting on weak/ permanently compressed springs causing bounce and hammering on the rocker as the cause. Here is a pic of 1 new, 1 compressed spring. Both from the same batch/ manufacturer built date. The weak/compressed spring caused valve...

Mine have all the bells and whistles including cryo treatment. 450# spring seat pressure, 1000+ at max lift.
