budget build 360

Ah, yea, shipping over the border is a bastard to say the least. I'd skip the Y/O create or anything in the U.S. for that matter because it is so crazy. I sent a guy something and he got hammered so flipping bad. I felt , horrible! I had no idea.

On the gear set, do what you want to do. The draw back of the high gear ratio is low cruise speeds on the Hwy. With my 4.10's and a 26 inch tire, it was approx. 3300 rpm at 60-65 mph. Some where around there. It's been a long time. But I would drive it several hours at a clip. I think the longest was a little more than 4 hours from NYC to DC.

That torque converter is ok for the cam you have listed. It'll all work well with 3.55's out back. On the pistons in the block, see where they come up to. At a zero deck height and OE J heads, the ratio is right at/about the 9.8-1 mark. But if the piston sit'slower in the cylinder, the lower your comp. ratio will be. You'll have to do the math on it to see where it is at. Then, you and the machinist can go from there.

Should the piston sit in the hole, that is OK. The ratio drop may be enuff. No more than 9.5-1 with that cam. Going higher is pushing it. I'm not saying it can not be done, but a bad gas fill will ruin the day. Or if the ocatane needed isn't available. Day ruined.
