Re: Thoughts on the stock 402?
.
Two bolt 1970 402 block, closed chamber #063 heads ( 101cc ), -15cc dome pistons.
That's all stock...mostly. Then I added comp xr270hr with matching springs, SS valves, proper valve job and setup, roller lifters, roller rockers and the correct length pushrods.
It idles at about 675RPM with a slight lope. Throttle response is IMMEDIATE with enough torque right off idle to pull a house down!
