Wow thank you guys for all the suggestion. F-Bird I like the cam choice you suggested. Are the Summit lifters ok or should I get GM ones.
The rockers are Summit roller tip stock style with 1.6 ratio. I never got around to getting full roller rockers.
I originally had a 3,000 stall converter in it, and it launched great but my gas mileage was about 8. When I did the last rebuild, (I had one of the Edelbrock cams from China and one of the lobes went flat chewed the lifter up and flushed it through the motor) I changed to the XE268 and it ran great never had any problems with it. It just for some reason developed all these problems while sitting over the last 8 years.
I would much rather just change the cam and lifters and not pistons and rings.
And I will definately look at the timing curve. I may need some help on that though.
