Fel-pros second design is metal with the rubber as well and comes with new bolts.

Have about 10 of these on the road with no issues. Just make sure you get the mating services clean-clean. Of course while you were in there you could have put a GM hot cam in it too.LOL


I am thinking the same thing with my Tahoe--when the engine dies--dropping in a 383 replacement motor right from GM.

You have to pull the heads off and have them machined to go over .480 lift. Stock lift is about .425 on them, and teh stock spring set-up is good for .450, the crane or comp springs and retainers can get you to about .480 safely, but to go more you have to machine the heads. In stock form the intake is VERY restrictive, and teh heads can use alot of work as well.
