I think we need to talk Adam into a shorter bar and raise the heck out of the ex. Besides, hes half way to a cant saw with no choke. Just got to drop the brake flag and it be on.

The exhaust doesn't need to be low to run a long bar,my 064 is 98 and runs a 50" nicely
I'm afraid of the intake duration getting to big and killing case compression, exhaust at 96 needs more intake than I want to give.

If this goes that way. Might as well get a head made with a pipe. I'm only planning on running a 28" max with a 11 pin. Lol

Wheres the intake now?

Wheres the intake now?

It is 100 117 78
I like everything but the transfers

 

[Moparmyway]

Cut 30/30
Let the JB set in the intake
Grind the exhaust roof
End up with 99/120/79

That's pretty much my exact plan if it don't improve with the big carb

Would some more intake help with the larger jug?

 

[spencerpaving]

Just throwing this out there.....went out and looked at my notes...my 066/056 is 98* ex 120 trans and 79 on the intake 205lbs comp

It could allways be lowered if need be after seeing how she is at 79

I got another cylinder coming to check timing on and I'm betting the timing varies on them. These are very high from the factory.
I was guessing 100 122 76 on yours
This cylinder had 16 degrees stock give or take. I haven't raised them at all and have 17 degrees of blow down and it runs exactly like a saw that needs blow down.
I have cut 020 or 030 cat remember without my notes,I know there is skirt left but I'm thinking the plug will hit with much more

 

[spencerpaving]

I believe you are correct on the varable timing....I built one for a good friend of mine and his trans were at 118....it runs strong but is lacking a little compared to mine

 

[RI Chevy]

Jason, where are you with compression at the present time?

I would love to get 100 120 78-79
I think I can but it would be giant compression.

 

[jmssaws]

190 or so.
The am piston through a 020 monkey wrench in my plans,020 shorter pin to crown but pin to the bottom of the skirt is the same.
Very poor design

 

[RI Chevy]

Decent compression.

 

[jmssaws]

Decent compression.

Really all I wanted.
I'm having a go at this 4 barrel right now

 

[jmssaws]

I moved things around and ended up at
98.5 119-120 78.5 and got this squared away

 

[jmssaws]

Wj35 066 carb on right,1050 dominator on the left

 

[Toad22t]

Wow. Hope the dominator doesn't get hungry.
