I have a 308 with trickflow heads, eldebrock intakes and so on, right now Im running a 26 inch tall tire in the back with 3.73 gears, would a switch to 4.10 or 30's be worth the switch?
Haha yeah sorry about that, It was in my sig and I forgot that I had changed it. Its a 308 long rod engine. 10.5 to 1 , custom grind cam, not sure of the specs lost the cam card. trickflow 170's ported to 180's. performer 2 intakes, both ported, 30lb injectors, 75mm tb, 76mm mass air flow, 1 5/8 long tube headers, 2.5 inch o/r h pipe hooker maxflow mufflers into dumps. no ac, no smog. t-5, mainly street this year, mostly track next year. I perfer the car to perform best on the track. Stock suspesnsion other than lowering springs and sub frame connectors. Power im not sure, haven't had it on the dyno, it really needs a tune. I assume around 300-320 rwhp the way it is. 6200-6500 rpm engine. Nitto 555r DR.5 speed or auto ? cam? which edelbrock...s....?, exhaust? suspension? intended use of car? track or street if both where u want to perform best? which trick flows? what kinda power does car make? what rpm? Slicks? drag radial? street tire?
More to it than what listed lol we can help just need some info bro.
thats why you put a chip in there or program the light to come on right before you need it to shift..:rofl:... I've been doin it for years in both cars..If it's a stock t5 I would go 4.10's with the 26's you'll want to shift about 4-5 hundred rpm above peak power and trap a little over peak as well. If your using a shift light program it to come on about 600 rpm before you want to shift. For the simple reason by the time you see the light and actually push clutch and pull shifter you'll be over your rpm. I learned this from mr Hemminger if you can program shift points for every gear you can get closer with the light in the higher gears because the shifts will not come as fast.
