Stock 340 intakes

With the cam I have in it now 6200 rpms is max, maybe 6000. Not getting valve float, just it stops pulling good by then.

Cranking compression is 160 psi, a little low for a 340 but it has the lower compression pistons with milled heads. 63cc chambers. The heads are the newer high swirl port 576 castings with the 2.02 valves and no air holes in the exhaust ports.

Drove it today, streets are still salt free, only low 30's outside and very windy. It runs great, idles good and low @ 700 in gear, pulls great but gas cost me $3.20 a gallon for the 87 stuff, which it likes as much as the 93, I can't tell a diff.
