On the final leg of my 383 build, comp beehive springs, 1.6 full roller comp rockers, 2.02/1.6 aftermarket ALU heads (+- 265 cfm intake at 600 lift), comp xr288 cam, vic jr, 850 holley, 373 rear, 3k stall, LT headers 1-5/8 or 1-3/4.. Wondering if the LS lifters are the same as the GM L31 ones? If they are indeed better then I will use them - Otherwise if the same and the LS can rev almost to 7k stock then the L31 lifters will be fine- trying to determine if and by what margin its necessary to spend $ on exotic lifters now or later- BTR has a set of LS lifters for $135 or there abouts iirc.. Thoughts? Its possible I might have the intake off for testing - so no biggy to swap lifters at a later stage..
