torque monster using 1972 technology. Extended lakewood slappers and a decent adj. shock, 9 or 10 inch tires. Doing a street-strip car like we had in 1972. Frame connectors but no cage.

what rear gear ratio?

330 831 4480 anytime

Odd that some people want to misrepresent helpful replies to a level of hate. ????? I live to help Pontiac guys understand how to get the most from their combination. You don't want my help, fine. Take your hate elsewhere. Long live my 8000 rpm Pontiac.

I remember when you told my friend he was over his head on a 1964 389 build. Remember the one where he reconfigured the combustion chambers on the 1964 heads, well it made 502 HP/500 + TQ with 18 inches of vacuum on pump gas, customer was sure blown away.............loves that car!

Bruce, if you know, how hard does Burton turn that ram air 4 in the lights? I would assume its well over 7000.

Curious...
How high does he spin the 389?
Thanks, Mike A114

That 389 was tested several years ago, and it wasn't tested by me, but I was there but can't remember the peak, I do remember the build because I machined it, low drag, well thought out oil system, a lot of detail work, a well designed engine that ran excellent in the customers GTO and still runs great to this day. Its important to note the customer insisted on using the factory 64 heads with the horrible valve angle. You can be sure it wasn't 7500 RPM.

Sorry Bruce Fulper my response was meant to be tongue-in-cheek cuz I truly am a moron where this pontiac motor is concerned I do not have a flipping clue how to make this mess perform properly. I truly appreciate each and every response and hopefully with enough help from class racer this car will run decently and not run over its own crank. My aim is to have fun and run decent. This is the last project I am ever going to do; I am old and physically beat up and really don't want to screw the pooch on this deal.
Again Bruce Fulper I sincerely apologize if you took my comments negatively they were not meant that way and I value your advise and it has opened my eyes to what I have to do make the car work right. THANK YOU

Jack Mullins 63 Catalina wagon…389/235…4 spd…SS/U circa mid seventies…

http://www.hotrod.com/articles/0212hpp-pontiac-history/

Mullins had what many Pontiac racers might call an aggressive driving style because that is what it took to win. He’d generally leave at 7500 rpm, shifting into Second at 6300, while Third and Fourth were engaged at 6800 rpm. He’d flash through the lights at 7400. “If I was in the final, I’d leave at 8200,” Mullins recalled. At that point I wasn’t worried about going another round. I could pick up 5 or 6 hundredths doing that.” Amazingly, he only had one bottom-end failure. “The crank did come out in three pieces, but that only happened once,” he said.

That kind of stuff only works if you are from Arkansas. We are way too backwards and ignorant to make "sofistikated" race car parts work..

I've always thought that many Ponco engines had bottom end oiling issues. I would certainly research this area before getting in too deep.
