Timmay!!!

Teksid block(96-99 cobras and lincoln mark VIII) , 03-04 cobra block? those should be good to around 900-1000hp. I'd point you to a good site where you could get some no B.S info on buildng a stout short but the mods would sensor it here.

Actually, the OEM aluminum block is good to 800 HP no problem. The trouble is the stock rods, pistons, and crank aren't up to it.

If you're looking for 800 HP or less, I'd stick with the aluminum block for the weight savings and becasue you don't need any funky adapters to bolt it into the car.

You might ask the big mod-motor builders like JDM, Fox Lake, Livernois, etc.

Thats what I was thinking but you know how it is other opinions never hurt. Before it blew yesterday it was making 500.3 rwhp and the factory componets finaly gave way. Guess its time to spend some real money.

Has Bennett Racing come up with anything yet? They were always a big time 5.0 builder...

^^what he said^^ The weak link isn't the block, it is the internals. Can't blame the block because a rod flew out of it.

What about some details, what power adder, what PSI on the power adder, and especially who's tune.

fox lake or livernois would be who i would go to for a good rotating assembly. forged rods, pistons, crank.


good luck.


what F/I setup are u going to go with?

Dont think it would really matter what or who's poweradder/tune 450+ rwhp on the stock internals is already a asking for a disaster. So he was really pushing them @ 500hp. A better question is for how long have you been pushing that hp?
