Must you stick with that CR? Can you not mill the heads? The LPE heads I had were for a 383/10.5:1 setup, but since I still had it on the stock block my CR was around 10.1 or maybe even less since they had a 60cc chamber.

Won't do jack squat by stabbing it with a ginormous cam that has no business being in there, but as stated. If anything your dynamic CR will be worse, but that's neither here nor there. Just do your thing and report the results.

Well slap my *** and call me Sally, then throw me down a flight of stairs and spit on my face while asking me while I'm so stupid. I thought I was aware of every chevy v8 motor ever made. This is news to me, and old too obv.

Are there any advantages to running the little guy vs the normal 350?

Sally.......no advantages. He just want to be the guy who does things a bit differently......and that's fine.

But there's different.......and there's wrong.

And a 243* duration cam in anything that has less than 383 cubic inches and at LEAST 11.5:1 compression is wrong.......

No such thing, just a vette servo which all Ls 4l60e's came with.

Sonnax makes a reinforcement sleeve that is pressed over the input drum where the input shaft goes in that is a good 4l60e mod and is cheap also.

With the little CID you will have using that cam profile, be prepared to stall and gear it to the moon. And when you get into a race with a stock Civic or maybe even a Geo Prizm for that matter, while you're revving past 7000rpm and still losing, perhaps then you'll come to the realization you did it wrong.

SS is just trying to give advice which he is right, the other day, Tuned an F body with a cam in the 250/260 duration range with stock heads, pulled the cam and installed one with 12* less duration, made 35 more horsepower. Just trying to sort out your combo..

It doesn't work like that. You could put a typical cam like the cc503 in there and have .25" on the intake and .35" on the exhaust. Milling the heads takes thousandths off, not tenths. A thinner head gasket will effect your PTV more than milling the heads. Also, changing the cam to have a few more degrees of duration and less overlap effects the PTV way more.
