The Mach has an aluminum block and cast internals, correct? Before I got my Cobra I thought about a Mach1 but decided against it because of reading that 450 was the MAX you could run safely before building the bottom end.Originally Posted by Mach'N'U
yep, like I said Mach's and cobras have an industry standard for how far you can go before buying yourself a new block.
Cobras are alum blocks with forged crank/rods/pistons, machs are alum blocks with cast rods/pistons and a forged crank. The limit for a safe tune via FI on a stock block is 450-460...anything past there and you will not last long. but most people detune for 420-440!
This is incorrect. Cobras have an iron block. Not aluminum. Daily driven/abused Cobras with almost 500rwhp are pretty common and those engines are still in great condition. I've seen a TT Cobra with stock bottom end, heads and cams make 873rwhp on race gas. Conservative street tune was in the high 600s.

dam always thought the cobras had alum blocks as well! But yes there are tons of twin and single turbo, and KB/Whipple stock bottom end cobras running around!
well, the Terminators are iron block. The New Edge Cobras and 4.6 SN95s are aluminum
Well, to play devil's advocate, Pro Line can build a 800hp-stable shortblock for $3600. An older Cobra (99/01) or aged Mach 1 with a Pro Line motor would be a great starting point for some serious numbers! The TR3650 transmission isn't all that strong, however, but could handle ~500rwhp for a while before blowing up.
holy fuck who have you meet that can drive around with a stock 3650 at 500rwhp?
But you are right on the starting points on those cars. MMR sells there FI Stroker 5L 302 Short block good for 900hp for $3299! I know because I should have gotten it when I did my shortblock!
