If I didn't say it before, this whole project took me 9 years. For one year it stayed in Roy's back yard until I could get a patio made on the side of my house. Then my total time was from 1992 to September of 2000. OK, now for a quick look at the engine. I showed the reciprocating parts in a previous post. Ross forged pistons, Crower forged rods and Childs and Albert's Zero Gap Second Ring (ZGS). I had the crank from my old 400 checked out and prepped for this engine and put it together. The cam I installed was a Comp Cam from Jim Butler. I've got a private story to tell if someone sees me in person. It's not about the Butler's, they're all good. The cam was 271/278 at 0.050" on a 106 LSA. I advanced it 6 degrees per their instructions. Now I put the heads on and check for valve to piston clearance. It wasn't a pretty picture. It was somewhere in the 0.040" range. The proper solution would have been to take the engine apart and have the valve reliefs made deeper. I didn't want to take the whole thing back apart, so I called the Butler's - again. My first question was what's the minimum VP clearance I should have. The said they make sure they have 0.080" on their customers' engines. So I asked them how close they go on their own engines. The answer was 0.070". So I did two things. I installed a head gasket a little bit thicker, and I moved the cam back to a 103 degree LCL instead of 100. I kept playing with it and checking all 8 cylinders as they are never exactly alike. CR ended up being 9.9:1, which is pretty low with aluminum heads.
B/T/W, notice the metal rods I had welded across the unsupported lifter bores.
To top off the engine I used an Edelbrock Victor aluminum intake and a 1050 Dominator set up by The Carburetor Shop. Brad Urban did my carb before he passed.
I'm all scanned out for the night, more later.
