LTX valve train on older blocks
Is it possible to fit LTX roller lifters in a early block? I understand the lifter valley would need drilled & taped for the roller guide plate and the front of the cam needs drilled & tapped for the cam locator. Other then that, will it work?

If you use a first gen roller block 1987 and up, everything will interchange. The LT motors just have a longer dowel pin on the cam to drive the optispark. It will also be a 1 piece rear main seal block.
You can't use the factory hyd roller parts in a older 2 piece rear seal block. The lifter bores are shorter, and it won't work.

You can't use the factory hyd roller parts in a Bowtie block. They do use the taller lifter bores, but you need aftermarket lifters. Dart has released their "Special High Performance" block that does use the factory hyd roller set up. It also comes with a big bore (4.125-4.165) and 2 piece rear seal block and crank set up.
