I have a friend who owns a 1998 GTP he claims that he engine is 400hp. He has these mods and I wanted to know how much hp he is really running. Can some tell me if its anywhere around 400.

Custom DHP tune
3" ZZP Modular pulley
ZZP Cam, 105 springs and lifters
Custom ported heads
Bronze guides
Stainless valves
SLP headers
50 lb injectors
Walpro 255 fuel pump
160° T-stat
Thrasher shift kit
Pro Tork 3200 stall converter
 


I have a built 1995 lt1 trans am. He couldn't handle my beast I was just asking because he wanted to sell it to me for 2.6k and thanks for the fast reply.
 
price really depends on how good the body is, any rust on the rockers or rear strut towers. not sure where bay is? but these cars rust out in the areas with snow.

KBB for a 98 is about 2000 in good cond. so try kbb see whats its worth in your area and go from there. as you know you never get your mod money back. not all of it thats for sure.

my other rule of thumb is also to never buy a modded car. best to buy a un molested one and start fresh.
 
his mod list dont say anything about the tranny either. stall and shift kit is only helping the beating its taking if its still stock. they do blow up. after that 350 hp mark you really need to install a load of hard parts. in short a good built tranny can add up fast.
 


350 Wheel at best if his block is a GT block, his "custom heads" are full blown hand ported and milled for compression, and he's running at least a shor stack full intercooler.

Even an XP cam can get close to XPZ numbers with the right heads

Verdict. He's a little over 300 imho
