Blew up the big block
 

well 11.5/1 compression and crappy quality premium petro canada fuel don't mix. When I tore the motor apart the piston in the #8 cylinder had a chunk taken out of it and at leats 2 piston rings are shattered, but luckily no other damage. In the past 8 years I have had that motor apart 7 times. Always stupid things like blown head gasket, broken con rod, bent push rod stuff like that. Just the romance of an old pickup I guess

Sorry to hear that Hooter. Is the bore smooth? Gas sure sucks these days. I've had good luck with homemade octane booster. The store brands are too expensive.

I have had the same problems in the past. A friend of mine turned me on to an additive of tetraethyl lead. It relly has helped as far as performance and pre-detonation. you can check it out at batterystuff.com. As far as I am concerned the only way to effectively raise octane and treat my valves right is with lead.

Yikes, don't get caught!

what's the recipie for homemade octane booster?

Homemade huh ????

Check out these octane boosters.

neonlarrys got it there! Stuff like that. The same chemicals at Home Depot are used in the store brands, except at 300% less cost. Except I use Marvel Mystery Oil for a lubricant. Its great for the valves as well.
