1966 330ci tuning question

[Mr. King]

I have a 1966 Cutlass with a 330, a 4 speed, 2 1/2 inch dual exhaust and posi rear with 3.55 gears. The motor is basically stock with a slightly larger than stock cam, an Edelbrock performer intake and a Edelbrock 650 carb.

The motor just doesn't seem to have any bottom end. It is very slow to rev and the motor doesn't really "come on" until 3500 rpms. Plus, it seems to "miss" at lower rpms.

I'm considering changing to a HEI points conversion. Anything else I should check or change. I set the timing to the stock settings and the carb is set just a little rich. The motor sounds great with a slight lope but it just doesn't pull like it should.

Any suggestions?

Small blocks will not have the low end pull of the bigger cube motors...however, I think your problem may be the Timing Chain. You mentioned the motor has a bit of a cam in it, I suspect that at the cam swap, the old chain and gears were replaced, and I have seen so many of the replacemant sets retarded. Most shops will not degeree a cam, so this problem is not found until the lack of low end is felt. I have built motors and have installed replacement timing sets " dot to dot "; checked them with a degree wheel only to find as much as 6 degrees of retard!!! Hope this sheds some light on your Question.
