QuestionI am building a 615ci (4.6" bore and 4.625" stroke) drag racing engine, compression: 15:1, I was wondering what type of supercharger to use (12 or 14 -71), also what gears should I use in my tranny (1-1.7) and rear end (4.56-5.57) for ultimate 1/4 mile performance, if you need more info ask, thanks.
AnswerHi Jay:
Sorry I can't help you , but I have two suggestions.
First get ahold of Summit Racing on their tech line. Their guys do know their stuff. Their web page is <<www.summitracing.com >> Look for the tech line phone number. It's a long distance call, but worth the trouble and cost. Also I have a distant friend who builds drag motors out west. Randy Cooper, write to him at <<fastcash@cehighperformance.com>>
Finally, there's a guy here locally that has worked in that end of racing, but he's going to be away for a couple of weeks. If you still need help by then, write me again and I'll try to pick his brain a little.
Good Luck
