Well talking to my wife tonight she told me to just put the money i would spend on headers and blower and put it into a engine build for my v.... So next mod is going to be taylor wires and tr6 plus and a tune.
BUTTT since i do use the truck for towing and I have these big wheels im going to be going from the 3.42 gear to a 4.10 gear. Should help my truck a lot and honeslty we dont do much freeway driving.
I have 305 35 24 right now with 3.42 gears at 70 mph im doing 1650 rpms
if i go up to a 4.10 at 70 mph ill be doing about 350 rpms more which isnt much
but heres where the kicker comes down low and im moving shift points to 6200 (which below shows) You can see stock 3.42 leave a lot on table
1st gear 3.42 gears goes to 43 mph
2nd gear 3.42 gears goes to 74 mph
3rd gear 3.42 gears goes to 114 mph
4th gear 3.42 gears goes to 151 mph
now going with 4.10s
1st gear 3.42 gears goes to 36 mph
2nd gear 3.42 gears goes to 61 mph
3rd gear 3.42 gears goes to 95 mph
4th gear 3.42 gears goes to 126 mph
305 35 24 70 MPH 3.42 GEARS 1650 RPMS
305 35 24 70 MPH 4.10 GEARS 2000 RPMS
350 RPMS not bad at all best of all is 1/4 mile.
Im shooting to look for 100 in the 1/4 with bolt ons
stock gear 100 mph is 5400 rpms in 3rd gear
4.10 gear and 100 mph is 4900 rpms in 4th gear which is still in the power band
I'm calling up gm tomorrow to order 4.10 gears
