    Yes, we live in Colorado right now. Your nitrous idea makes sense but, power adders is never a option in my shop ever. This truck has a story, and it started out as project for my 15 year old son to learn how too: 1. Find and buy a virgin engine old school SBC core no one would bother building...

    My Rear End Build For My Low Buck Street/Race Truck

    Thanks, gears, and rims were changed, never did get the aluminum drive shaft built yet. Converter flashes 4200 RPM, but I need around 5600 RPM. It drives just fine in town on the street and we drive it very often.

    The 60 foot is horrible. 1320/104.93=12.57. Next changes: 1. Fuel system 2. Ignition system 3. Aluminum drive shaft 4. 360 inch small block 5. Loser converter Done racing this year. The drive train has a horrible amount of weight, you combine that with the altitude, the truck just will...

    In my opinion the truck should be raced in the 5600-7200 RPM range. I never see below 4200 RPM on the track now, thats why it isn't faster than it is.

    Converter is aftermarket, I will change the converter after I make a engine change. The 327 build was a project for my son to learn how build a engine most people wouldn't waste their time with. We did race Sat. If you have a TQ peak @ 5200 RPM, where do you want the converter to flash?

    My Rear End Build For My Low Buck Street/Race Truck

    Yes. Actually what I need is another 1400 RPM of converter flash!

    My Rear End Build For My Low Buck Street/Race Truck

    I think its important to mention I never seen high gear with the 3.07 gear, I ran through in second gear. When I ran 13s with the 3.07 gear I was fully hooked up (no spin) with the open rear end with a 30X9 radial slick with 30 PSI. 2.17 60 foot. The 327 really didn't like the 3.07 gear, really...
