these trucks amaze me

Yeah... that was definitely an unfair fight, but awesome nonetheless!

cool

Also like stated by Aquawolf, this truck competed with some of the fastest street cars being made at that time. A 13.1 1/4mile was as fast or faster than a lot of very expensive exotics, and also a bit faster than the street sports cars of that time like the Mustangs, Camaros, 300Zxs, and even the Supra. But, the Syclone had same un-noticed problem in common with a similar car before it, the Grand National. That problem is that both of these vehicles, the GNX and the Syclone, are faster than GMs flagship sports car the corvette. Ever wonder why these 2 VERY fast vehicles had production ceased so quickly? GM could never allow the obviously supporior boosted 6cylinders of that time to out accelerate the corvette, no way. So they burried them, just like the GNX. The corvette simply wasn't as fast as it should've been, at the time GM did not refine what was selling, they're cheap. So great and unique ideas like an AWD Turbo V6 truck, and a turbo V6 grampa car got burried for exposing GMs unrefined, overdue performance car the slowvette. They got it right now tho of course.

Some of you that are talking about the engine used in the syclone and the heads that came with it are incorrect. The GMC Syclones and Typhoon engines came with LB4 heads, not vortec heads. Vortec heads came out in 1996+ S series trucks. The name Vortec on the engine had come out ealier than that, maybe 94 or 95, but it was simply a marketing name, real vortec headed 4.3s only existed 96' and after. Now, what Syclone owners do, is trash those garbage LB4 heads they come with, and bolt on a set of late model Vortec heads for a very nice power increase, anywhere from 60-140 more HP, CPI heads (L35) that were around even before the vortecs are also commonly swapped in place of the LB4 heads for a nice power increase. But, the vortecs are hands down the best Iron heads you can put on a 4.3 motor, and arguably better than any aluminum heads for they're unmatched high air flow @ .500 valve lift and below

NICE!!

Back when these trucks were made, it bested even Ferrari's of the day in 1/4 mile and corners. They have a 60/40 torque split front to rear and have seen daily driven street versions put down mid 9s. My question is, is the crank a common pin or split pin? I've never found out.

I have actually blew a hole through the front transfer case already.

boost launching isnt only hard on the tranny... 700r4's and 4l60's can be built to 600hp capabilities

you swap in the 4l80 which can be built to 1000hp+

the t-case, differentials...the whole driveline takes a beating on boost launching

the syclone engine was vortec, it was the first of the Central Port Injected, it just so happened to be turbo.

they were vortec engines.
