460 is at the machine shop. i expect it will dyno at 400 hp and 500 ft lbs torque or close anyway. i am going to run a c6 trans and 3.25 gears. i know traction is going to be an issue. tires are 255 60 r15. what can i do to help this truck hook up a little. i got some time before i get it installed and just want to do my homework. thanks for any input i really apreciate the wealth of knowledge on this site and enjoy learning abut these engines!

Really depends on how much you want to spend. About the most cost effective way would be Cal-tracs. Don't get me wrong though a good tracion bar can be very helpful. With them properly installed the adhesion of the tires will be your limitation.

I agree cal tracs or a good traction bar. If you dont drive it too much try the Et Streets they hook real nice, I run them on my 79. A detroit truetrac or full detroit locker would be my choice for the rear end

I run a truetrac in my superduty it works real well I have killed both rear tires equally and left identical marks on the road LOL

traction

You might look and see if "No Limit Engineering" has a ladder bar suspension for your truck. I use their ladder bar on my 1955 F100 , its made to work with the factory leaf spring set up, and is a bolt on deal. It uses a 32" bar with a floating front pin, so it shocks the suspension similar to the way the "Cal-Tracs" bar does. Its worked out well, no wheel hop, and launches straight, hooks hard.

Mickey Thompson drag radials, traction bars and a detroit locker, Randy.
Yep,That will do it.
Currently I'm running 315/60 E.T. streets,spool,and the "gasser" bars from S&W.Just have to know the roads and watch the weather when I take it out.

Big Daddy, I have a very similar combo as yours, but mine is a '78 F-150 LWB with factory helper springs on top, no traction bars, 3.25 Detroit Locker rearend-not true trac(that is a limited slip), and M/T ET drag radials-P275/60-R15. My truck weighs 4,860 pounds makes similar horsepower as yours and runs the quarter regularly 1.89 60ft and 13.50'[email protected] No spinning but it helps to have a good VHT-prep track like ours down here in South Louisiana.
Hope this helps.

HI, I will have closer to 500hp and a little more torque. My vehicle will be 99.9 % street driven, BUT....before I make it heavier,(it's a '56 panel truck), with full interior, sound deadener, a/c, etc., I think it would be cool to take it to the track and get some pics and video. It will have a C6 and probably 3.25 gears. My questions are: 1) Do you guys like the 3.25s for street driving and can a Locker be driven on the street (lots of turning)? Currently it has 2.75 open 9" 28 spline...I know, I know, but I got a great deal on it. Pardon the hijack:eek:,
thanks,
James

If you have a locker that unlocks both directions they work great for the street. There is a locker that only unlocks to the left{ Nascar I suppose } I have found 3.50 to be a great street gear, but a 3.25 will be fine. If you have to buy this stuff go with bigger axles, that way when you build that stroker motor, you know you will, you'll be ready, Randy.

truetrac was the one i am looking at as it sends power to the wheel not spinning however i realize it is not as strong as a locker. those pics would be nice. looks like im on the right track thoug i thing this truck will come in around the 3800lb mark. got a while before i do the diff and yes i will buy the big axles! thanks!
