Hi,

How big is too big with the stock computer understanding that it in conjunction with the MAP are the limiting factors?

ie. Is the Wade 1521a to big for the stock computer?

What is the limiting factor? Is it Lobe separation? Duration?

Cheers,

I've heard that a 1521a is too big without a chip. A unichip or chiptorque chip are needed.

the limiting factor is manifold vacuum. the EEC is set up to run with
19 inches at idle. larger cams reduce this, get to far from 19 and it wont idle very well at all.
both lobe separation and duration have an effect on it.
