Thread: Finally Building the 350 this week... what do you think about the setup?

He actually hasn't done a bad job of matching the cam to the compression ratio. I figured the ratio at 10.7 with a zero deck and 0.041 gasket. The problem that I see with it for a street motor is the compression ratio. If he backs off on the cam, the motor turns into a turd because the dynamic compression ratio will be in the crapper.

He can, of course, keep on with what he has, but like others said so far, you ain't gonna like it much. It will be fun for about 10 minutes. After that, you'll be kickin' yourself.

I don't like electric fans, but do as you like, it's your money.

One way we could try to "bleed off" some of your comp. ratio is to have the cam ground on a narrow lobe seperation.
We don't know your exact comp. ratio.
Will this be enough to keep the engine out of detonation?
It is really hard to tell.Every engine acts a little different.
We don't know if the block has been decked,have the heads been flat milled ,angle milled?
I would look at some on the smaller Crane hyd. cams for drag racing.
In stock form your heads have an exhaust to intake ratio of approx. 68 %.
To help with the detonation and help with the exhaust side of the heads I would look at a Crane part # 110591 cam.Specs. are in. lift.480,Ex. lift .494,
Dur. at .050 In. side 228,Dur. Ex. 234,lobe seperation 106.
Will this work?
I don't 100% but you will be much closer.
Anyone else have any thoughts about this?
