vfast

can I ask how you arrived at 385hp?

Thumper Performance

You could but then I would be giving up "Speed secrets" LOL JK... We are the most complete machine shop in the midwest. We do low volumes of HIGH quality work! We do the best work for the least money. This is what we love. We have a few extra builds that we decided to sell outright to the forum memebers. We have four Chevy motors, 355ci shortblock, 383ci complete engine making 450HP, 510ci BOW TIE blocked dart headed conservative 800HP complete motor and a 427ci alchol blown 2900HP motor. We do serious things to the usual suspects. I will get you the facts and figures on this perticular unit (Ford 351) and send them shortly. If you would like you can call me (480) 266-7439 Thanks for your interest, Mike

OK vfast I got down to it earlier today...We have been building these Windsor 351s' for along time. This motor has never seen the dyno, I can say from experience that I know this exact set up (built by us) is in a 71' Mustang and on the dyno with a 650 and a mechanical secondary it made 402HP at the crank after the math from the whp was done. Same cam, same head work, done by my boss and same internals as well as the Airgap. This motor is a build that we did for a Mustang I once owned but a newer project came along. The guy who bought my car did not want the engine as it did not suit the direction his build was going. As you probabaly know the 351 is the strongest SB windsor ever built! These things take gobs of punishment and then ask for more..I am only selling to make a little more room in the garage for the new project FI 347...Thanks again for your interest..
