SPF sidepipes needed
1 Attachment(s)
Any Bay Area folks out there have a used set of Superformance side pipes they could let me modify for use on the dyno?
I just did some preliminary dyno work on the all iron 483ci tunnel port I built for Gene G. With small, economy 1-3/4 truck headers and a carb problem that is only allowing about 2/3 secondary throttle blade opening on both carbs, the engine made 565 hp and 565 lbs torque. The hp was made at only 6000 rpm. The pulls were made on pump gas and 36 deg timing. If I can find a good set of headers and get the damn secondaries open all the way it should make well over 600 hp. Thanks, --Mike |
Wow, it looks like you can get some HP out of a FE but not a 514?
Oh gotta go,by! |
SFfiredog , I have an extra set but I'm in Pa.... What carbs are you using on the engine pictured?? I just finished an aluminium 427 with tunnlewedge and am looking for different carb selection for it ..Tried 2 600 OEM carbs . now have modified 450's ...THANKS Steve McD SPF 1287

Thanks Steve,
I got some pipes. The carbs are 725 cfm Road Demon Jrs. They work well but don't call Barry Grant for any advice. The tech guy I talked to literally went ballistic on the phone telling me the carbs weren't designed for that... the cam was too big... so on and so on.... I told him to calm down and hung up. I made them work but I don't know if I would recomend them to anyone. At 289.00 a piece the price is right though... --Mike |
