    Nice 75 Cutty, I had a 75 Cutlass supreame myself, Black with white stripes. did it up as a 442 clone. it was a 350/350 car, 2 1/2 duals w bombs of course. :) only had 66000 when I got it off my uncle spent my entire grade 9 year and most of grade 10 restoring it. got it painted Black with chevelle style white stripes. drove it everyday to school until my OAC year. best car I have ever owned unfortunatly it met its demise when I was hit by a drunk driver coming home from a bar. car's front end was totaled. IV built a number of cars since including a fully restored and hot rodded Camaro, and my present project my 63 Pontiac Stratochief lowrider. but I still cant stop thinking about that car. I missed it soo much I had to buy another one. I just bought a 75 Cutlass 4d with only 30000 on it also 350/350 the interior looks like its never been drivin little old lady owned. so because Its a 4D im planning a Pepsi Blue Paint job and Hydo's (What else can you do with a 4D :) ) I live in Thunder Bay, Ontario where I also run a Car Club Stylin Concepts CC. my E-mail is mbonazzo@hotmail.com if you wanna see a pic of what it could look like black with white stipes E-Mail me and Ill get a Pic of it to you online. Anywho good luck with the car and never ever get rid of it. It will come back to haunt you. :) peace

    Nice Cutlass, I think it's sweet that your building an awesome 403 SBO, I think that 450 hp and 500 tq, might be a little optimistic, i think 450hp is possible but with a 3.385 inch stroke, 500 tq is a little unreasonable, 500 tq is more easily possible with a bigblock and a 4 plus inch stroke. I think that you will be more like 450 hp and 450 tq. How high do you plan on reving it? If you were to put a 425 olds crank in it (which require clearencing the block) and offset ground it you would have a 480+ cu/inch small block! Now that would be a torque and hp monster.

    wassup i just put some dynomax headers on my 455 in a 77 supreme. i had a small clearence problem on the driver side put they fit just fine. the headers are ceramic coated and also came with a lifetime warranty that covered rust for under 300 bucks. i ordered them from jegs. check out kingcut i have a picture of them on my block.

    (What the hell it didn't show up the first time, I'm so sick of this so I selected my text and hit copy before i sent it so I'm repasting it all and trying again) Hey what's up? Yeah I was really fricken relieved once I had the headers in that's for damn sure cuz there's no way I can return them to summit after 6 months, I'd be SOL! But I guess I got lucky and they ended up fitting really nicely too after all that pain. Yes I painted the inner fenders too with some special plastic black paint. It actually turned out really nicely. As far as the tranny goes I'm ordering the B&M Transkit from summit for 216 bucks or whatever and I'm actually about to order that as soon as christmas is all over with. I'm gonna clean up all the parts in our parts washer, take it down to pieces and put them in labled bags and I have the 75 Oldsmobile GM service manual that has step by step pics to go through the transmission, though I'll be swaping for pieces from the B&M kit which includes a Full Manual/Auto kit and the shift kit. I already have a B&M holeshot stall converter and once this is all done it can go in and be started up. There.... lol, talk to ya later!
