Whatever cam I go with I want it to take advantage of the ported heads and have good driving manners. I drive the Tahoe at least 4 days a week to work...

 

Subscribed! That engine is going to make some serious power, and love the vintage orange block paint job!

 

The cam in my vette is 219/231 .607/.617 115lsa. Pretty close to what you're considering. I thought it might be a little big for my truck. With your extra cubes, that thing should be about perfect (in my mind anyway). Should run hard with boost, have excellent manners, and even have decent fuel eco numbers. I don't think you'll be too far off running that cam. It may not have the sound the identifies you as running a cam that's stupid big, but you'll like it in just about every other way.

 

Actually the lack of chop is good for me. I like it to sound pretty stock.

 

I'm thinking just a little more lift since the heads should breathe pretty well...Waiting on Ed Curtis to get with me. He has a suggestion but I didnt have time to talk to him again before the holiday...

 

Leading Edge Performance has two good FI cams. Joe at Leftcoast32 recommends them. I'm running one of theirs in my 370 with a front drive TVS.
I'm making 16psi on a 2.9" with 8 rib and 10% balancer. Joe can hook you up on pulleys and balancer too. Check it out, he has a new website. Just search for "leftcoast32".

 

Since I'm still deciding how far to port the heads, what do you guys think is a good CR for a 408/2300? I have been shooting for 10.5:1 but was thinking mabye even 10.7:1 might be ok. 91 octane gas and MAYBE meth for safety but not tuning for it timing wise...
My understanding is the cam choice can effect yout CR as well...

 

10.5-10.7 will be great for the TVS. I'm right at 10.5 on mine. Still makes good power out of boost.

 

Do you not have access to 93 octane?

 

If you go too high you are going to have a bitch of a time tuning out knock, lets face it you see some warm temps in the summer. Your cam can have a large effect on cyl. pressures as well.
