Working on an LQ9 build for ethanol or methanol and would like some input on cam selection.

6.0 bored 4.030
12cc dome pistons for 6.125 rods and 3.622 stroke
Stock 823's
LS3 inatke but am leaning more towards the EFI Holly High Rise with a 102 TB
99 GM ECU with 2000 Z28 engine harness but may opt for the Holly EFI

Will be running PG or TH400 with a MWC Fab 9 but not sure on what size ring gear yet. This is going into a 99 Camaro that will be running on a 10.5 slick.
Eventually I will want to throw some boost at it so if anyone has some suggestions on a cam and injectors I would like to hear from you.

Thanks

 

How much boost you looking to throw at it?

 

Not sure how much I'll be able to throw at it but was thinking 10-12 for starters.

 

A good cam for boost will be different than a good cam for N/A. Cant have both. What kind of RPM are you wanting to turn?

 

 

12cc dome will limit your boosted app down the road unless you stay around that 10-15psi mark. De-cap LS3 injectors (mine measured 84# per hour but you'll need a lot more injector later on for boost and ethanol) and if you go with the Hi-rise intake then definitely go with the BTR/Lil john stage 4 turbo cam. It will make good N/A power, not ideal, but will still make good power.

 

I'm getting roughly 12:1 based on a zero deck and a 0.060 gasket. I'm thinking it will respond well to ethanol with methanol injection and a little boost!
