I'll post pics of bits necessary to convert your Impulse this weekend. It's best to use a drill press of some sort, that way you can keep the recess in the chassis for the mounting screws. You should definitely do the conversion. You will not regret it. I can't seem to get the out of control imports link to work. How can I contact them? I REALLY need those pulleys. Big block tends to eat stock drivetrain parts. Good racing.

Here is a pic of the bit I used to enlarge the recess in the chassis. It is best to use drill press of some sort. Just set the travel stop on the press so that it can't go too deep. That way you keep the recess in the chassis the same thickness.

This is the bit I used to enlarge the motor mount holes in the chassis. I also used it to shave the motor mounts down. It is a carbide bit, very sharp. Although it won't be quite as sharp when you're done. There is a lot of cutting and grinding involved. Many metal splinters. Totally worth it though. The few people I've let drive my car are all believers now. Guess there might be more big block conversions running around soon. Just wait until my .21 is done Good luck and good racing.

Hey guys I just picked up a used Impulse the other day. I was wondering if just replacing the shocktowers and new Pro rear uprights would make it pretty much the same as the Impulse Pro. I already have the radio plate, chasis stiffeners, centax clutch and 2sp. tranny, and belt tensioner along with a Pro rear diff. that's externally adjustable(uninstalled). I don't plan on getting the front one way yet until I'm a better driver. Any reccomendations would be greatly appreciated.

Does anyone know the drivetrain ratio for the Impulse???? I'd like to figure rollout but I'm not sure on the ratio.

Well the rear diff pully is 46T and the layshaft pully is 23T.
so the ratio is 2.

Thanks Eddie.

vthondabio, I have the Pro kit and eveything you mention is in the kit. If you want a Pro, get the towers and a front one-way. The Pro kit is just a bunch of optional parts put in the kit. Everything should be readily available. If the car "feels" good driving it, I wouldn't change anything. If anything, make small changes.

thanks for the info Terror
