If you had Lath, you could have made some nice round spacers. That's why I bought one. If I only power had power connected already.

I've been doing all the same kind of stuff this week for my truck. About to put the transmission back together tomorrow, got the engine ready to go a few days ago. I suppose it would have been more fun if I weren't sick doing it all lol. Those valve covers do look really nice.

[@ImpalamansGarage]

Thanks!

[@ronstjohn6780]

That engine is looking mighty, mighty good! I like the fact that you retaining basically the stock look. I guess you have decided to retain the original a/c system?

[@ImpalamansGarage]

Yes. For now. Need new refrigerant hoses and condenser though.

[@ronstjohn6780]

I did the C4 blower motor upgrade on my ‘75. It helps a lot with air flow. But you’ll need a spacer to make it work. I have an extra if you need one.

What the compression ratio of the engine now? Did I miss it on the last video?

[@ImpalamansGarage]

Unknown. Originally it was 8.9 from the factory. That was with 76cc chambered heads. Pistons are flat topped. The new heads are 64cc and the block is .030 over. So very rough calculations guessing at piston TDC to deck volume, gasket volume etc.... I'd say around 9.5:1. It will be somewhat more than stock but to measure it correctly you need to fill the chambers with fluid. I'm not doing all that. LOL.....

[@vintage76vipergreenBeetle]

@@ImpalamansGarage I thought you did all that stuff, and I just miss the video.

[@jamesbush268]

Starting to look like your shop is shrinking. You going to add on?

[@ImpalamansGarage]

Some day!

[@donopp5850]

Your intro had me scared ... I thought you were going to leave the block unpainted and a hodgepodge of many colors. I guess I should have read the title more carefully. A shame to paint those pretty heads though ... I get the stock look thing, but I would guess that anyone looking at your engine compartment ... you're probably going to tell them they are aluminum anyway. I might have stuck with the thick valve cover gaskets ... Just that much more clearance for your rockers and goofy valve cover tabs.

[@ImpalamansGarage]

Yeah. I'm on the fence about those gaskets. I might go thick. They just seemed excessive to me. My cam is not radical to the rockers are not sea-sawing in there. The engine shop primed the shot block so it had some paint on it when I painted it blue.
