340 buildups

I don't know how set you are on a 340, but I might suggest the Mp 10:1 360 short block. You can get them for around a grand. I got one of those, put a .450 Mp cam, stock x-heads, edelbrock performer rpm intake, 1 5/8 headers, 2.5" exhaust. That coupled with 3.21 gears (8 1/4 rearend), I ran a best of 13.19 @ 106mph.
