Fully Forged 383
TEA Stage II heads
Port matched intake
Comp ProMag 1.6rr's
GM 847
PS LT's
Custom True Duals
36lb Injectors
11.8:1 compression
The car is still in need of a dyno tune, all it has at the moment is a tune from Ion at MadZ28 for my stock cube motor with the 847 and 36lb injectors. This tune was for different heads, different intake, 1.52 ProMags, and only 10.8:1 compression. The guy that is going to be tuning the car for me is currently out of state so we are trying to set something up for next Friday or Saturday.
Anyways, here is the video:

93octane, pump gas I don't want to be out of town somewhere and not be able to get fuel for any reason.

It was understanding it's never a good idea to run pump on anything bigger than 10:5:1. I guess not.

That may be true on Gen I SBCs, but LT1s can tolerate much higher compression due to the reverse flow cooling. I am well over 12.0:1.Originally Posted by DRIVEFASTKEEPLEFT

LT1's love compression and big cams. 
reverse cooling helps that. generally 11 to 1 is good with pump gas and aluminum heads. LT1's can go abit higher
But todays gas is getting abit crappier with more ethanol content and other crap they are putting in it. Its not a bad idea to keep compression down alittle bit just to be safe. Or to throw in a gallon or two of the good stuff

what about 91 octane with 11.7:1? Thats the highest octane we have here. I have been running 91 for awhile and i wonder if this is why we are having trouble tuning. Maybe thats the cause for running rich?
