5.7 Tbi Vortec tune.

[Fast355]

Ok been tuning my newly build engine and have the tune in the ballpark. I am putting my Bin up as a start point for those who wish to use it as a start point for there build.
Engine specs are as follows
350 bottom end with a 395 GM cam (no advance or retard)
Vortec Heads with 1.5 ratio roller tip rockers
Static compression ratio 9.8-1
GM vortec to TBI inlet manifold bored out too 2"
Holley TBI with 65lb injectors
Fuel is our standard Australian 91 ron
ECM 16197427
Base tune Eprom BJYL

Hope it helps some one who has as similar set up.

I had a very similar setup in my Express van except it had the L31 Marine intake. Great engine for low-end power but couldn't pass a dump truck on the highway with that cam even with 1.7 rockers. Dumped that cam for the GMPP 357 HP SPO 350 crate engine cam. If you someday decide you want more power the SPO cam is worth about 50-60 HP at redline over the 395' cam with nearly no change in low-end torque. My converter stalled 2,700 rpm with the 395' cam and about 2,800 with the SPO cam. So noticeably more powerful even that low in the RPM range.
