Thread: What gives the L36 Higher Compression?

Considering you'd have to run headers or a cam or intercooler just to run the 3.8, yes.

My searching suggests the L67 pistons must have a larger dish in order to lower compression and increase piston-valve clearance.

It was still slow.

I should have dyno'd it so we would have had solid information.

it made 267 STD on a 3.4 pulley with rockers at 5200-5500 est RPM.

Never took it higher because I failed to hold the car in third.

With leaky valves and some odd compression numbers while churning out liquid metal every oil change.
