Harris Family

I know how to go to TDC. I just used #1 as an example. Give me an ounce of
credit here guys. All cylinders are wrong. The head must have been
resurfaced as well as the block. I went down to Crower this afternoon and
they gave me an adjustable pushrod and a Mechanical lifter. I'm going that
route. Unless you guys can give me a viable alternative.

PS I've rebuilt a bunch of engines but never had to resize pushrods for a
hydraulic cam.....always a first time....I'm going back to GM small blocks
where you can mechanically adjust.

No Bill, it's all the cylinders. I just used #1 as the example since its
where any good mechanic would set an engine when tearing into it.
