Been thinking about my next project. I'm getting tired of hearing about the mega HP GM's and Mopars being sold for $70K- $80K to rich kids. Time to build a lighter, quicker, faster sleeper. From my point of view, a blown DOHC modular with electronic engine control is the best way to get there vs. using the Windsor or Cleveland platform. The engine would go into an 83 to 86 T Bird that would look bone stock, save for wider rubber and lowered stance. Opinions?
Sounds good to me, I had a '03 Marauder with 4 valve that made 430Hp at rear wheels... Of course it was basically a stock motor on 10psi boost, with ported heads, more cam and boost, decent exhaust system etc there was still lots of power hiding... Drivability was as good as any modern fuel inj vehicle, idle all day with A/C on and with 3.55 gear, get 22mpg on highway... The Italian Teskid aluminum blocks used in the MK VIII is said to hold 1000Hp... The Marauder used a WAP block(I believe Windsor cast) that is good for approx 800... The stock Marauder rotating assembly is good for 10psi but it's said that the max if longevity is is a concern...
I'm thinking DOHC because you can go with less aggressive cam timing with 4 valves/chamber. As you stated, the factory blocks are very strong also. The fox chassis Bird has a large enough engine compartment to accommodate it. I loved my 3 valve SOHC Mustang when it came to both power and mileage. Just got tired of passing myself on the road once they became common. Never liked "common" hot rods.

Yeah and they are probably 350lb lighter than the tubby T-Birds, of course the Birds can be put on a diet fairly easily... Brian(I bought Comet from), has a sweet Fairmont Futura with a 393/C4 combo I believe he said it went 11.03 best(or mebby that was the Cleveland Maverick, both run similar times), currently it's apart for a turbo install...
Don't forget the old rule too.. more cubes = more fun. You can easily stroke those motors. Look at John Kasse's engine masters motor to see how big a crank throw that oil pan rail can swallow up with no camshaft tunnel getting in the way. Obviously need to rethink the added compression if your huffing it up but that's what dished pistons were designed for anyways.
