Home port the heads. Simple and doesn't cost anything except time and a grinder. Someone posted the old porting templates recently, maybe in the tech section. Mill them if you can with a good valve job.
Old school 284/484 108 LSA cam installed at 100-102 with a new timing chain using the stock low comp piston. Get an cam you like cut on a tighter LSA and install it a bunch advanced, isky 230/480 would be another. The 284/484 can use stock style rockers, bonus!
Find a torker/street dominator/rpm intake and a 750-850dp.
Curve a stock electronic distributor and give it a lot of initial timing, total in the 36-42 range.
Hone the cylinders, new rings and oil pump.
Go beat the snot out of it!
Yep.
It's not going to have perfect ring seal, valve seal, or last lots of miles. but you just build for a little more HP to account for the little losses.
