LASHWAY MOTORSPORTS | TYRANT 427 - BUILT LS7 98' Trans Am Convertible TYRANT 427 | Lashway Motorsports
Lashway Motorsports would like to introduce the LS1TECH community to our newest build, TYRANT 427 a ridiculous 1998 Convertible Trans Am.
TYRANT 427 is owned by Mike Nowak of Palm Beach Florida. He brought us Tyrant as an already modded 1998 Trans Am. The Trans Am had a mild heads and cam package on the 96K mile original motor, but as any F-body owner knows it is never enough. He told us the plan, drop a built and cammed 427ci LS7 into his convertible Pontiac among a huge list of other things…… and uuummm nitrous…..
It was then decided Tryant could use a little work in the paint and wheel department. So we teamed up with Superior Auto Design and had them custom paint Tryant PPG Lamborghini pearl black and take care of any of the custom vinyl you see. While the soon to be monster of a car was dormant in paint the mod list continued to grow into what it is today.

427ci LS7 SWAP
22x/23x MILD CAM

No, I do not believe so. If anything, the ports were cleaned up a bit. Otherwise, stock LS7 heads and a small cam. All of these parts we're already installed when we got the engine here.
Start with 100, and go from there. I cannot imagine EVER needing anymore than it has NA haha...
Thanks Buddy
Thanks!
