OK here's the deal: I have a '84 Coupe with the dreaded crossfire system. I just recently found out it has a Turbo 350 trans in it. Is that good or bad? I have true dual exhaust with no cats, no pollution control stuff, rapid fire plugs (big deal I know), Ram air mod, new wires & tune up kit, '91 Fuel pump and am running syn-blend. I know these things are not as fast as other years but this thing isn't really all that bad considering it's a "ceasefire" I put new 255/50s on the rear (others were bald) and from a dead stop the old car will light them up into 2nd gear. If I tromp it from a stop (no powerbraking) and leave it in Drive it will burn through 1st and then shift into 2nd while still spinning. If I manually shift it & watch my launch, I can get away with less spin & then when it hits 2nd the assend hooks really hard and squals like a "scalded dog". My old '79 would burn them off if I started off by powerbraking, But this one has much wider tires under it, and can put on a "show" at command (thats with brand new rubber no less) just by floorin' it. As far as performance I easily beat a GP GTP from a dead stop to about 70 before we had to shut down. It really p.o'd the pontiac driver cause he knew I had a crossfire & he thought he'd beat me. We tried using my old G-tech but had trouble getting it level. I got one run of 6.2 for my 0-60 so I don't know?? BTW, I also know (the hard way) that I am avearging about 8 miles to the gallon--Yea 8 mpg, But thats with driving the crap outta the thing too. I know nothing about trannys & gears etc. & I know nothing about the car I bought. I didn't really care because it is just kind of a toy to mess with. Here are the "ratios" for the stock trans & the transplanted 350 turbo--
700R4 TH350
1st-3.06 2.52
2nd-1.63 1.52
3rd-1 1
4th-.7 N/A
Whataya Vette'sperts think? Thanks for any info BTW. Also I don't think my old Crossfire is bad@$$ or anything I'm just surprised it even has as much punch as what it does.
