so there i was at 11pm and i decide to set my engine at TDC to set the rockers and low and behold my valves are touching my pistons when i bar it over. i have 63cc heads with .040 cometics, flat top pistons, 1.7 roller tip rockers and my deck height is stock. are my head gaskets to thin?

 

fixed my issue. here was the problem.



and i thought this was just amusing so i took this pic of the old 5.3L piston in the new bored out cylinders just to show i size perspective

 

That's a lot of meat out of those cylinders but a 1/8" bore job still leaves a lot there. I have 9000 miles on my 383 and have never had a hint of overheating or any other problem for that matter (and I beat the **** out of it). It just gets better with age.

My Crane rockers had no clearance problems and have been flawless in operation. Do those ones sit high?

You're getting close now, keep it up.

 

those were my rods hitting the windage tray. my PRW rockers hit the valve covers so i had to buy 1/2" spacers

 

Glad to see its coming together!

 

im stepping out into the garage now to set the rockers and drop the engine in right now. ill take pics of her installed tonight.

 

Sweet lots of pics

 

just set the block down and put 2 bolts in the mounts. tomorrow ill bolt up the transmission and the exhaust.

 

Looking good

 

picked up my spark plugs today. what gap do you recommend? stock or other?
