How about some help?
Ok this is actually a few questions here goes;
My current setup is a 402 BBC in an '89 S-10 with a TH350 no brake 3500+ stall, truck weighs @ 2400lbs running a 9" with 4.56 gears on a set of 31" slicks. I'm getting things together to change trans setup to include a brake. My main question is this, if I put a glide in should I go with a different gear and also will I need more stall. I only run 1/8 mile where I'm from. Will I need to change alot of internal parts to stay together or will stock hold up? I've put in extra discs & clutches in the one I have sitting in my trailer but nothing more. I know I will change input to turbo. Any help appreciated. I'm on a budget here Thanks, Dave

IF I WAS YOU TO FIGURE YOUR RPM AT THE TOP END FORMULA IS THIS.....MULTIPLY 336XGEARXWHAT MPH YOULL MAX OUT AT THEN DIVIDE BY TIRE DIAMETER...EX,100MPH TIMES 336 TIMES 4.10(REAR GEAR RATIO) DIVIDE BY TIRE DIA OF 29 INCHES=4750 ADD IN A LITTLE CONVERTER SLIPPAGE DEPENDING ON IF ITS TIGHT OR SLOPPY,5% IS ABOUT AVERAGE.......TOTAL=4987.5 RPMS@100 MPH!!!
AS FAR AS POWERGLIDE DONT KNOW,SHOULD BE MORE CONSISTANT THAN TURBO TRANNY,BUT A STOCK T400 IN STOCK FORM SHOULD HOLD UP NO PROBLEM,AND WILL BE A LIL TORQUEYER CAUSE OF MORE GEARS...GOOD LUCK,ID PUT A T400 IN IF IT WAS ME!!!
