Re: Its Mine the World Famous 67 Dragtruck

Hey Kevin, what length are your primaries? Headers look awesome by the way, I pulled my truck out again and have a ****load of changes being made to it including a new motor, my setup is going to need a 28” primary. My headers will be fenderwell also, I’d like to somehow do it so I can use a couple v-bands off the slip on merge collectors to hang a short 5” exhaust to dump behind the cab that I can take off at the track but not so sure it’s going to be possible.

Not a option this will be on a race motor primary size, merge collector size and length will all be specific to this motor, it will be around 1200hp. Exhaust is just to keep it quiet around the house and to meet requirements to run in street car events, will be dual 5” minimal and light attachment will have to be right off the collector so once removed motor is at optimal running N/A.

For heads up street car events with exhaust I will have a 200 shot of spray to compensate

Anyway sorry to derail your thread Kevin, was just curious as to what length primary put your collectors at that position.

I keep forgetting to measure the length but I think they are real close to what you are looking for. I plan to add some short Race mufflers.
