Need advice on a Vortech build up for a 383.

Looking for low 10's and not real concerned about staying streetable, and price isn't a real big concern.

I currently have a 350 4 bolt roller block, Sprtsman II's, Demon 750, Air gap and all the other good's.

So i guess I'll need a Forged stroker rotating assembly, new froce induction friendly cam and some other odds and ends.

I'm curious about how low of a compression ratio to run. I'm not real sure on how much boost I can run , with say 8 to 1 or less <?> static compression, and 12+ lbs of boost on 93 octane, if 110 is needed.

Kinda a 'vague' post any and all info is appreciated.

I was researching for SC setups, and came across this article below on holleys www site. I'll probably try to follow this during my build.

I just have a few questions:

Whats does it mean to O Ring the block ?

I like how my 350 rev's up, meaning that I'll hit 6500 with the quickness, would a 383 rev up in the same manner ?

Thanks

For maximum boost and horsepower applications (12 pounds or more), we recommend the following engine specifications:
High quality forged or billet crankshaft
Four bolt main caps with quality bolts or studs
Steel harmonic balancer or crank hub
High quality steel rods (H or I beam)
Forged blower pistons
O-ringing the block (mandatory)
Severe duty stainless steel valves or iconel
Fully ported and polished heads
Solid or roller cam designed for high boost
Roller rockers
Chromoly push rods
High output ignition management system or magneto
Blueprinted carburetors or fuel injection
High octane race fuel (112+ rating)
Minimum of a 3" diameter dual exhaust with free flowing street/race mufflers and large tube headers.
Recommended primary tube diameters and collector sizes are:
Small Blocks: 1-7/8" to 2" with 3-1/2" collectors Big Blocks: 2-1/8" to 2-1/4", with 4" collectors
Maximum effective compression ratio on gas not to exceed 24:1

 

A 383 will rev up just fine. It'll make more torque down low because of the increase in stroke. O-ringing the block is where a machinist cuts a groove around each cylinder and puts some stainless wire around it so it sticks up off the surface just a little. It will "press" into the head gasket and make it to where it seals better. Highly recommended for boosted applications. As I said in the email I sent you, my heads are o-ringed. I have a killer setup for you. Mine will include everything in that paragraph. Let me know if you are interested.

 

instead of o-ringing I went with the special part # of felpro with the ring in it and machined the heads. They are called loc-wire gaskets.

 

Thanks for the info guys, spooled I'll be in contact with ya..
