My engine has the modifications listed below in my signature. It's an '84 block with flat tappet lifters & cam. The engine mods were done by a previous owner and I do not know the cam specs. I have a worn lifter and am in the process of disassembling the engine to remove my lifters. Dyno results with my current set up are 227 RWHP and 255 lb-ft of torque with a broad torque curve (>200 lb-ft from 2000-5500 rpm, >230 lb-ft from 3100-5200 rpm).
My question is, "Now that I have things pretty well torn apart, are there other changes I should make now?"
I'm considering having the heads ported and the intake extrude honed. Is it likely that the cam is worn because one of the lifters wore down? Should the cam be changed for other reasons? If so, what specs would be recommended for my set-up? My understanding is that converting to a roller cam is not worth the expense, but correct me if this is wrong.
This is a street car. Thank you for your help!
