A BIG THANKS to all Thirdgen, and ChevyTalk members, and also Sallee Chevrolet for the details on what componets to install in a third gen 383 roller motor!

I fired it up today!! Have about 15 miles on it now! Can't hardly sit here and type this. http://www.sallee-chevrolet.com/Chev...eeZZ450HP.html

Anyone care to guess, or run this through a Desktop Dyno, and tell me how much HP/Torque I'm making? Notice I said "MAKING" now instead of "going to make!"

638 .030 over 1990 or so roller block, zero decked
Scat 3.75 crank
Eagle 5.7 rods
SRP 11:1 pistons (flat tops)
SLP 51006 Hydraulic roller, 3 degrees adv. built in
int: .495" 270 218
exh: .502" 276 224
Comp cams timing gear and chain
TrickFlow 23 degree aluminum heads w/.039 quench
1.5 Harland Sharp roller rockers (Need 1.6's maybe?)
Accel 74197 intake, SLP runners, Ported plenum, Air foil
Huge K&N filter, 3" SS pipe, in and out of the MAF
22# injectors, stock pressure (to be changed soon)
Hypertech chip (soon to be a custom chip)
373 gears with 295/50/15 rear tires
A 700r4 that's been modified and shifts great
Hooker full length headers with 2.5" all the way through dual two chamber Flowmasters

It idles like a dream with enough lope anyone who knows what power sounds like can appreciate it!

All in a 1989 GMC pickup, 4040 pounds with driver.

Thanks in advance!
