I learned recently (from Ebrig) that the compression ratio should be calculated for the entire stroke (swept volume of the piston full stroke)

So calculate (displacement/2)/(dome volume + head gasket displaced volume - piston dish volume)

couple questions?

What is the current port timing?

What is your target port timing?

Can your target port timing be reached by these means?
I don't have the numbers infront of me. I believe the transfer port durasion was 128 and I want to get it to 123-125. It seems that the 60t cylinder has much better port timing and I'm going to map it out. probably saturday. Decking the bottom of the cylinders will get the port timing in a better range.
 
I don't see why not. you can pull a motor out of a sj and put it in a blaster without changing bedplates.

Yeah that's what I'm thinking. The only things is that the blaster motor mounts are straight while the sj motor mounts are angled.

Who knows if I can figure out a way to easily mount a 66e in the blaster and find a pipe that will work I may have to follow in your footsteps Tim.:scratchchin:

I'm looking for low budget power too.:bananajump:

The port timing specs for the GP800 are as follows. The transfers are 128 degrees, exhaust is 200 open, 185 with valve down. There are alot of things that determine where you will want to be. There is no one perfect place. Everything changes with bore size, compression, etc. I have figured out some really good set ups, and anyone that is doing the conversion can call me and I will try to help you go in the right direction, right "DEMON"? By the way, how is that custom manifold coming?
