305IrocZ28

My car (supposedly) has 145k miles on it, and the engine still seems to be running strong...however you can never be too careful with these things. If I ever had to get another engine, what engines could I swap in? (I talked to a guy with an 82 Z-28 who swapped in a 350 from an 84 Corvette...claimed the car ran a 13.1 et)
How much would other engines go for? (used, new/crate, junkyard)

I just turned over 142k on mine. I'm hedging my bet by running sythetic oil in it to keep it from wearing out any more than it has. I changed intake valve stem seals and intake gaskets, oil consumption dropped dramatically. High-mileage SBC's can last a frustratingly long time when you're looking for an excuse to put in something more powerful.

I seriously doubt that "guy" put that '84 Vette 350 in stock and just started clicking off 13.1's - he did a lot more to it before that started happening.

As for what you could put in it, any '87-later style used, new/crate, or junkyard engine could be swapped in. You could create your own with a World Products Merlin 434 CID short block, put on AFR heads and a healthy cam, Bigmouth or Miniram, headers and good exhaust all the way back, connect the subframes and get some gears, do all the standard tricks (injectors, AFPR, chip, tranny beef-up, etc.) and be in the 12's.

Price would be around a grand to reside in the 14's, several thousand to get into the 12's.

I would have some doubt about a guy who's making 13.1 with a stock 84 corvette engine. he had to modify something to ran that fast .

Don't think that 305 has had all of its miles yet, mine has 197,509 as of today and burns about a pint of oil between oil changes. It just needs valve seals. I am currently building a $2000 383. It has an Eagle stroker kit, roller cam, ported and polished heads, and roller rockers. If you can do the work yourself you can save about $2000.

I beleive an 1984 Vette came with a 305. I'm not sure of the induction type, but it was the first year w/the C4 body.
