Engine specifics haven't been decided yet as for forged and dished and what not... but...

4 bolt 383 stroker
Paxton Supercharger W/ blower cam (7-9 psi)
Current Trick Flow Aluminum Heads
Accel Superram set-up
58mm throttle body
Crane Roller Rockers 1.5
etc

What are some estamates for 1/4?
This is planning for a weekend warrior that I want smoggable.

Anyone have any USEFUL COMMENTS OR CONCERNS? Thanks!

 

sounds fun

 

we can't help you with 1/4 mile estimates or smog legality until you share your ultra top secret cam specs. Just saying blower cam isn't good enough. If you need help picking one, just say so.

 

Sure, just need a cam that will provide good power and still allow it to pass smog. Im not too picky or knowledgeable in the subject.

 

If it was mine, I'd order a COMP 12-000-8, 3015/3037-115, and NOT use 1.6:1 rockers. That's still .537/.536" valve lift at 1.5:1. I'd also suggest COMP 26918-16 springs installed at 1.75"
Polish the chambers and exhaust ports of your TFS heads, too.
With the above, 1.75" SLP headers, dual 2.5" cats, and a 3.5" or 4" cat-back, and a suitable intake manifold, you'll still pass emissions, and have power to 6500 rpm. That's your shift point with this build. At 9 PSI, I'd expect over 700 crank HP. You can do that with a production block so long as it doesn't have any core shift or cracks. a cast steel crank will survive if you can keep it away from detonation. You do need pistons forged of 2618 material, the 4032 forgings won't do. you can tell the difference by the suggested piston to bore clearances. 4032s are around 0.002", while 2618s are around 0.005". This means they're noisier when cold. I suggest polishing the tops of the pistons, and deburring everything, including your spark plugs.
You do need plasma-moly rings, generously gapped. MLS gaskets are fine for this build, no need for O-ringing. Do use ARP head studs.
Also pay attention to your PCV system, it needs to be in top condition.

 

Wow, that's for the great info. That's everything I was looking for!

 

Be aware that this'll still have plenty of exhaust backpressure. Not a problem for a 1/4-mile blast, but if you're going to the bonneville Salt Flats, or any other such sustained high rpm, you'll need to temporarily uncork the exhaust in front of the cats.
Dual 2.5" is still a restriction above 550 crankshaft horses, for race only use, you'd want dual 3". Not legal to try dual 3" cats, however.
