how much would say this is worth, and do you think its a good idea or not and do you think the engine will be strong and last.

1998 Pontiac Trans am, black/gray leather, t-tops. Automatic programmed shift points/rev limiter. the crank and block have 130,000 on them but all the bearings and gaskets heads cam intake all have 10,000. the rear end and trans are new as well.

Corvette ZO6 heads, cam and intake
3.73 gears
FlowMaster LT headers, y-pipe, and SLP loudmouth exhaust - no cats/has O2 sims
SLP intake, tranny cooler.

Professionally dyno and dyno-tuned at LS1speed.com (Speed Inc) by Tom the "Master"

427/436 TQ

Comes with NX nitrous kit, never installed. Includes bottle heater, remote bottle opener, purge valve and all of the goodies possible. 10 lb bottle. 50-150 HP gains possible, all jets included.

 

i think it's some BS going on.

first off...it's not a ZO6 heads, cam intake...

it's the LS6 heads, cam and intake

and i HIGHLY doubt you could dyno tune a ls6 upgrade to make 427rwhp...

that's what most guys with low 23x cams and heads dyno...and the LS6 cam is MUCH smaller!

now if they calculated the crank hp and that's what they mean by the 427...than i'd beleive it. cause that calculates out of 360-365rwhp.

 

The guy has the dyno sheets to proove the hp but i dont know if its at the wheels or crank

 

i gotta agree with teke

 

dyno sheets of the same car? I dont think so. 427rwhp is alot for those mods. From the information provided, he basically has an LS6 engine, tuned it, and made 22 more hp at the wheels than a Z06 comes with stock. Sounds like he is either talking about hp at the crank or lieing.

 

Since when did Flowmaster start making headers?

and as said, 427/436 RW is highly doubtful from an LS6 (basically) with full exhaust and a tune. At least I don't believe it.

 

Maybe those numbers are on the juice???

Even a Z06 is usually in the 350-360 whp range on a dynojet. Thats a big difference from 427.

 

That's not gonna happen, especially on an auto.

You're looking at a 340-350 rwhp car tops.

Anyway, I wouldn't pay more than $5k.
