SIG-054

Hey guys,

Ive got some Mast Small Bore LS3 heads on order along with a pretty good valvetrain (1.8 yella terras, .700" K-motion springs, 3/8" P/Rods, morels) and im now looking for a cam to suit it. I want to run some good numbers down the strip as well as on the dyno.

It has a Circle D 4c converter, built 4L60e, 3.9 diff gears and will be tuned on E85.

Daily driver too but i still want a decent sized stick because i can

How much extra clearance do these heads provide?

Ill probably be getting an ISKY grind through my local tuner as he thinks they are a lot easier to tune and they run nicer. But ive been pretty happy with Comp in the past.

Cheers
Tom

I say go with a Comp Cam, they can help you with cam selection online, just click their tech support instant messaging link.

Sounds like your gonna have a nice build, what kinda bottom end you got?

SIG-054

Standard bottom end, but with sump baffles, modded windage tray and ARP rod bolts.

what do the heads flow ?get a custom cam for heads that great.

Thats where im stuck, dont know what size (in the 240's would be good), duration split or LSA to be looking at? Am i looking at something that suits a rectangular port head design or more of a traditional LS1 design?

You might want to ask the folks at MAST - likely have a good idea what works with their products.
