Yep, wnats under the nood is a mistery!! A better cam...this and that... Dont forget, i fixed the truck up to tow our 5yh wheel trailer. When its not towing it is a beast to handle!! If i floor it from dead stop, it will grab rubber, same when it shifts from second to third as well. When it rains, its real hard to keep it from just spinning wheels. It just scares the hell out of people sometimes. Anyway, its still a bear to drive, but fun too!!
