351C Stroker project
Here we have a 351C stroked 4"
topped off with the CHI 2V heads and an Edelbroc air gap intake.
It should get warmed up tonight.
Comp Cam 32-250-4

hey Tim, any chance of better a graph? the scales seem to be in a forgeign language and kinda hard to read at that.
24 degrees total timing, was that just an arbitrary number or did you do some 'sperimentin? what ignition? how much initial? any vacuum?

Hope that is better, sorry about the double post.
The distributor did not have a vac. advance. I was not involved that much in the dynoing.
24 advance is the max for the peak power. These heads are very efficient, so I knew it would be low. We started at about 20 & went up.
The engine was dyno'd on 91 oct. pump gas.

I need the rod length, and static Compression Ratio. Also Carb size and Bore.
I don't have that cam in my files, can you give me the specs: Advertised and @0.050" duration, lift, LSA, and ICL.

to me it looks like a very very solid 400 build but scaled up 1000 rpm. Any reason a stroked cleveland would spin better than a 400? Cam spec would be nice to know.

You can get the cam specs off of Summits website, just enter the number: CCA-32-250-4. Maybe this link will work:

OK, got that. I set the ICL at 106 and ECL at 114 degrees.
Now I just need the Bore, Rod Length, and CR.
