I'd like to see your car back itself out of the garage first before I make a statement

Once I get the battery back in it runs fine, and yes reverse works too.. Next question do you also agree that my power band will only be from 5000-6400 rpm then it will fall on its face?I'd like to see your car back itself out of the garage first before I make a statement

Can we get a spread sheet of the shift rpm drop per gear to prove this theory? I really don;t see anything wrong with a 3.23 equivalent gear at the top end? Everyone says turbos like Load, that is load...at the top..In other words the 4.10's + overdrive are probably not a good idea.

What RPM do you want to see in each gear? I am planning on running eights this year. I want at least 152mph. The regular combination of TH400, converter slipping less than 8%, 3:42 gear, and 28" tires should go through the traps appox 6300 - 6500rpm. So why not get it done in that rpm range?

Last year when I went 154mph with everything you listed, I went through at 6800rpm (9.5"PTC spec'd by Dusty). Mind you my 60foots were terrible, but I can see more rpm with a better 60 foot out the back door. I can't see a 8sec Buick with those specs doing 152mph at 6300-6500rpm through the traps. IMO you have to stretch the legs out in 3rd to get it done, unless your car is a mid 8sec car and your taking a easy pass to get 8.90's.
Who's to say racers aren't using 3.20ish ring and pinion? Depending on the combo it may be required. The 153mph example I gave was with a 5 disk vig. I know others have been that fast with a 9.5" PTC and very similar hyd roller. The converter was pretty tight comparatively to what most would use. Rear gear/converter needs to be adjusted if the mass flow is increased or the engine rpm will be too high. 154 is solidly 7sec mphGNDriven said:So how is 154 MPH not 8's territory?High 8's but 8's
The TCI calculator says 6700 for 153 at 6% slip, or 6800 for 152 at 8% slip. Either way I hope to muscle to whatever the RPM is required in 3rd to reach 152mph.

Norbs, what does your car weigh? You have an awful lot of gadgets and stuff under the hood. It can't be light. Power isn't everything.
I would say its about time you put you freeze any more changes to the combination and get some track time or at the very least spend some time on a chassis dyno....
