Hey,Good Buddy!....hope you stow away a few SLEEMAN'S in that there trunk! Lookin' forward to quaffing a few with my buddies...who,unfortunately,I don't see nearly often enough! Rick...I agree with Brad...won't know the answer until you try some! I'd start with a 50/50 mix of 93 pump and 110...see if it improves ANYTHING! If so..maybe bump up the ratio to 60/40...or 70/30. One of these days that's what I plan to do with the GTX...even though mine seems to run without any signs of detonation at all. 10:25 compression,aluminum heads...and 38* total timing.
