Update !!! We have been working on it pretty much all weekends so we are about to make it run
we will obviously need a tune.
Most likely an emergency tune, because we will swap the complete
intake / EFI system to get rid of the old spider.
Here's the mod list :
L31 Bored .30 - 355 Now
Flat 2 valve relief Hyper Pistons
AFR 0912 Heads
GM Hotcam
1.6 Crane Cams Gold Rockers
1 5/8 Long Tube Headers
Taylor Vortex Spacer
Taylor TB Spacer (Not sure if it works but we did it anyway)
Spider Upgrade (we got rid of the old poppet style)
AirRaid Intake
AC Delete
Underdrive Pulleys
Yank 3600 Torque Converter
We will try to make it run next week and i think it will run decent but ....it will idle like hell.
I did this very same thing on my L98 Corvette and i needed a tune to get a decent idle.
But i got the Ostrich and
Chip burner that was eat cake! But this is not the case here.
We will raise the budget for a complete EFI Selftuning upgrade, the stock intake will be a bottleneck
and will leave lots of potental out ...well, raising the money might take a few months so we want to
drive it for a while and we would love to have our options. As far as i know the blackbox cannot be tuned.
What i was thinking was to buy an already tuned blackbox guided by my mod list.
Any recommendations? Who can do this job great and right? Any help will be appreciated !
ps : we don't want the hassle to do the 411 swap since the new EFI set up is on our plans.
Or ...maybe yes and it's not so difficult ?????
Thank you !!!
