OK so here is what I have gathered for my options:
Option 1:
1. Heads & Intake from a 68 SBC will bolt to a 02' 5.7L Vortec short block.
2. Use the pushrods from the 02' Vortec, Use the rocker arms from the 68'
3. There is no hole drilled in the block for a mechanical fuel pump rod....You will have to use an electric fuel pump.
4. The water pump bypass hole is not drilled in the block, Use a water pump gasket as a guide to drill the hole.
5. Install a melonized distributor gear on the 68' distributor.....

Option 2:
1. Utilize the entire new motor and buy a new intake:

2. Recommend replacing the weak vortec springs with some LS1 beehive springs. Comp cams makes special retainers (
http://www.compcams.com/catalog/COMP...12_353-355.pdf) call help line for comp cams for this and the beehives don't require machining like the double coil springs do.
3. All your mounts and accessories should bolt up no problem.
Optional to go with a serpentine belt setup from a 91 Chevy pickup w/350TBI engine.
Avoid Astro van serpentine setups, everthing mounts backwards from standard.
Option 3:
1. Leave the internals stock and throw a new intake for vortec heads on it and go with a new intake(

Look OK?
