Hi guys, I'm new to this and new to Big Block Chevy's. I'm having my bottom end built out of a 427 tall deck truck block. However a little confused about what kind of top end to buy. I want between 300-320 cc. intake runners and 119-124 cc. combustion chambers for heads. Any ideas for what brand? Anyone know where to go for a dual plane intake?
My application is four wheeling so I don't need real radical stuff.

You can get more interest if you post your question under the ENGINE TECH section of this forum.

I can only talk about a 496 from a drag/bracket race combo.

320 heads like DART PRO 1 325 or RHS 320

119 combustion chamber.

12.5 compression.

Roller cam .725" lift, 276/284 duration, 110 lobe seperation. (Best to get a professional cam guy to make the selection once everything else is known.)

Single plane intake, Edelbrock Victor R.

1050 Dominator carb.

Forged crank and H beam rods with L-19 bolts. Eagle quality or better.

2 bolt block is OK with ARP main studs, line honed.

Best machine shop you can find.
