i just picked up a 350 4 bolt main engine. wheni ran the numbers on the block i found out that it came from a 87 camaro. now my questio is about the cam .after inspecting the block and cam i noticed that it has non roller lifters in it but has the roller lift hold down plate holes in the center . now is it possible to run regular hydralic lifters in the motor ? cause if im correct in 87the 350 offered came with a roller camshaft. need some light shed on this

 

Yes, both styles of lifters can be used in those blocks. It appears the cam has been changed at some point, and they changed it to a flat tappet cam for some reason. If the towers in the lifter valley are machined and tapped, the roller stuff will fit right in.

 

thank you thats what i wanted to know i hate posting on here sometimes because peole dont answer your question they like to argue the other points of the paragraph instea of what you orinially asked . thank you very much i was really unsure of that

 

 

Trucks used the same blocks as passenger cars, but didn't have roller lifters. Some of the blocks weren't even finished machined for the roller provisions, but many were.

But, if you're sure it came out of a Camaro, it should have had roller lifters. Make sure the pushrods are the proper length - roller lifter pushrods are shorter than flat tappet pushrods.
