my buddy had an sbc engine built by a roundy round engine builder that was built for a street car. he ued all old blocks and steel heads with no explanation why. even used a solid flat tappet cam that only goes up to 6200 rpms and dont really start working till 4000 rpms and there is poor vacuum for...

hey mag2555. thanks for the reply. he does have a fuel pressure gauge mounted (i think) on the outside of car by windshield and he did say he had around 7 lbs of pressure. i dont know if this was always the pressure under load and running down the road(maybe it drastically changes when running?).. h...

anybody with even a little tip on how to unscrew the diaphragm? thanks Art

have an older barry grant 2 port regulator that was never used and i know there was a problem with the hockey puck type seal disintegrating; i have the rebuild kit with the new type vitron hockey puck seal and new diaphragm. really cant see how the diaphragm spins off the tiny brass shaft. looks lik...

hey steve cowan pinion angle is definitely not the problem' years ago John Calvert explained drive line angle to me very well. too many guys out there quoting angles and degrees but nothing is in relation to anything or what the moving parts of the whole picture were. im not saying you are one of th...

hey mag 2555 i dont understand the part of disconnecting the brake thing. he has some hi tech hydra boost brakes on car and i think they run off belts (is that possible) thanks art in ny

hey mag 2555 i believe your assessment of thi problem is exactly the way i was looking at this problem. checking the timing as the car stall out is a great idea and your final conclusion is one of the things my buddy brought up at the very beginning about bad intake gasket . any suggestions on how t...

went to friends house with one of my good carbs. car does the same thing with my carb as his does with his carbs within about 200 RPSs. starts up, rev it up a bit, and let it idle down and at around 1300 to 1500 RPMs it cuts out and also diesels back through the carb. he says the timing at around th...

i checked back with by buddy and he now tells me it stalls out immediately when he just starts it up sitting in his driveway and not moving. in other words he just starts it up, it runs for a few seconds and cuts out. same thing happens when he drives it and comes to a light. in other words, it just...
