it dynoed 457hp@5300 rpm and 503lb ft tq@2490 rpm not to bad eh? the guy let me do the first run on the dyno i sucked he told me i waz shifting all wrong? how the **** you do that as long as it goes in the right gear?ne wayz dats wut it registered

 

holy ****! who built the motor?

 

um i think eather you cant read or the dyno is realy ****ed up. 500 ft lbs or torque, a crapy V6 dosnt have enough stroke to make that kind of power. my friends 396 Chevelle can even spit out numbers like that at the rear wheels, and his motor was built by Ken Murry(#1 enging builder in my home town)147 hp and 203 ft pounds of torque i would beleve however

how does the 406 compare to your GNX? I'm debating several engines: 385 vs. 406 vs. LS1 vs. T3.8L

the only reasone I'm leaning away from a t3.8L is that I'm getting tired of the auto tranny. I know a guy in San Diego that can get a whole LS1 setup for $5-$6k: radiatior to rear end. he parts out and also fixes 4thgens

 

o hmm yea i hear you i just swapped in the manual too so thats prolly why ill go 383

I expect to do somewhere in that area with my TTA. I've put my numbers into the the program to figure out HP using you ET and weight and it came up with 405 HP. That 's running 12.42 @112. The car should be in the low 11's once I get back on the road in a couple of months. Maybe 475 to 500 HP by then.

Pete

 

He got that 540+ on a carbed engine....Ill see if I can snag his build sheet from him one day and Ill post it here
