well after almost a year I replaced my 305 TBI with a 350 vortec tbi. Love it !

350 .030 bore
scat crankshaft
recon rods with speed pro pistons,moly ring set
ported vortec heads with minor porting
milled and a serdi profile valve job
backcut valves for better low lift numbers
stock 98 suburban hydraulic roller cam !
performer intake with TBI adaptor
ported throttle body with injector spacer
350 injectors with 18 lb spring
balanced internals

I installed a 350 chip from a 89 g20 van from the junkyard and it fired right up and I was kinda happy. I new the motor was off and was expecting that with the mods and HP increase,
Well I ordered a custom chip and WOW ! Like it added 75 hp ! Smokes the tires from a roll ! [Linked Image][Linked Image][Linked Image]

You put it together yourself? Nice job you got a chance to get it to the Dyno yet? Where did you get the chip?
