LQ9 Build Suggestions
Hi everyone,
I just picked up a low mile LQ9 from an '04 Escalade that will be going into my '67 Camaro, and would like some suggestions on what heads and cam to go with. I have a T56 arriving later this week.
My first thoughts for the heads were stock 243/799's or L92/LS3. Someone else suggested a set of 5.3's, but I heard they don't flow as well, just give a compression bump?
Important info:
- I will be using an Edelbrock Vic Jr. EFI intake with a 4 barrel throttle body
- This is not a daily driver, but not a strip car either, so driveability is somewhat important
- Budget is always a concern...
I want the Vic Jr/TB setup so it kind of retains that old school look, but with the advantage of EFI. I know that the Vic Jr. is better for high rpm, and gives up a little on the low end, so I'd like to find a set of heads and cam that can pick up some of that low end grunt. Once I figure out a set of heads, then I can start thinking about the cam. Also, I already have the Accufab 4150 TB, I don't have the Vic Jr. yet since I know they make one for the cathedral ports and one for the rectangular ports.

What's a better option?
-Higher flowing heads/smaller cam/higher compression (ported/milled 317's)
-Higher flowing heads/bigger cam/lower compression (ported/unmilled 317's)
-Lower flowing heads/bigger cam/higher compression (stock 243/799's)

Won't I run into PTV clearance issues if I have the heads milled too much?
