I had a 383 in a 1995 5 speed with a holley 670 cfm TB and 454 injectors. After 51 custom burned chips I gave up as well. Sold the engine, put a junk yard 350 in it and sold it.

iamkeniff put a gen 4 5.3 in his 94 ecsb complete with lts, cam, custom tune, and 3000 stall... his build is in the projects section....

Probably mine. I've been changing things and messing with the tuning literally for a few years now and there are still some lingering issues but its coming around. LT4 hot cam, ported vortec heads, single plane high rise intake, 454 throttle body, and an otherwise stock short block with a measly 202,000 miles on it. On paper it should be in the 420 hp range and similar torque. In its current state it may do 400. Who knows it may surprise me if I ever get it on a dyno. TBI is very finicky when it comes to tuning. The latest advent is Mass air. It actually works very well. When I put the LT4 hot cam in I literally turned the key and drove it. I had to make changes to the spark table and some minor tweaks at idle but other then that, that was that.

Kurt, Ill bet money you dont break 350hp with that setup

I think silverado myke (sp?) has a small block 350 in his nbs....dunno if its TBI though.

I think he is running a carb, no injection.
