My friend had a TT 89 Callaway vette. It was stupid fast. I loved that thing. Its most of whats fueling my search for a C4.

I was at Guldstrands when that happened. About the sametime Guldstrand took a 1988 Corvette (GS80) to Talladega and ran 184 MPH. That is naturally aspirated 372 with a modified TPI that put 380 at the flywheel, stock body no aero tricks other than tape off body seams.

Well... actually, it was DG's personal GS80 with a Traco 377 cid, the 4+3 ST-10 transmission... with the only 'modification' to the TPI being the Siamese runners and a ported base manifold... it also made more than 380hp at the flywheel. :secret:
Oh yeah, and the 184mph... was the average speed for 24 hours... a current standing record to this day. The only thing the car did was come into the pits for fuel... while four guys running out of a Goodyear Trailer with four wheels and tires wrapped in black 55 gallon trash bags until they could stuff them on the car without exposing the tread designs that they were testing.
Those are the good ole days I miss working for Guldstrand...
Guldstrand did all of the suspension modifications for Reeves back then.

It's not hard to see where Lingenfelter got the inspiration for his later C5 twin turbo Corvettes.

Have anyone done anything like this recently with the newer Vettes?...I can only imagine what they could do with all of the HP that can be squeezed out of this LSX stuff and the slicker C6 body.....vs a C4 with a TPI

Guldstrand did all of the suspension modifications for Reeves back then.
It was Bridgestones car at the time and was later purchased by Guldstrand. The traco was a 372 (new bowtie block no over bore yet) and the early cars were 375 to 380 with the solid engle cam (later ones got to 400 I heard). The Bridestone Corvette did set a 24 hour speed in TX but it had a stock L98 in it at the time, and wasn't 184 MPH. I had to rebuild the suspension when the car came back from TX and install the Traco after the around the clock running in TX. The 184 MPH was at Talladega AL with the 372 Traco in about 1989. Actually at the time that car was on stock Corvette suspension and not a true GS80. I used to love test driving it on Jefferson looking for Porsches and other exotics to beat up on, I would have loved to have taken it to the street races just once, man with the race fuel chip that thing flat hauled. The 1989 Hot Rod Camaro was a ton of fun too (ya sure Jim Jones it is a 305.......RIGHT) I really miss working at Tricky D!cks too.
The tires being put in the bag was in the very early 1980's with a GM development Corvette (before the C4 released) when Goodyear did the tire that became the Gatorback. The Black GS80 that Guldstrand now has is a 1988 that was used to develop the RE71's and the tires for the ZR-1 Corvette (315-35- 17 God they were monsters at the time).
