475/500 HP Range on 89/93 Octane
If you're going to r&r the engine, you'd be much better with the 383.
Dyno results:
(1) 383, Dart iron heads, 9.5:1 (Ross pistons)C.R., Comp Hyd. Roller-retro, Eagle crank(int. balance), and Edelbrock intake. This one came off the dyno at 460HP@5700-447Tq./4700. Has exc. vacuum readings due to size.
(2) Identical short block ***'y with the exception of the C.R., we upped this one to 10.4 due to using Brodix Alum. heads (190CC) on this combo.
This came off at 480HP@6100-453Tq.@5100. They both run on 89 in decent weather, however, both customer use 93 all the time. It's always better to have more power than you need (I'm not sure that's even possible), than not enough when you need it! Thanks, Gary in N.Y.
PS We're much higher now with the numbers, these were two straight-forward jobs, with NO add'l head work, etc. We tested with the customers components (pipes & carb), most benefit from parts changes in the dyno room, but don't want the additional costs incurred.

BADDD- I just sent you the vids of Les's Z28.
GOFAST- I eventually want to build a 383 stroker, or maybe even something bigger, but right now I can't really aford it. I only have about ~$1000 to spend on motor mods because I have some other work to do on the car. Hopefully next year I'll have enough extra money saved up for a bigger motor.

Dyno Test from Gary
Most motors are tested with open headers and no accessories, no air cleaner. The street engines, as the ones in the post, were tested through mufflers. They're pretty free-flowing however, and again without any belts in front and no air cleaner. We run outside air directly into the carb. We try to get our customers to supply their headers and their carb that they plan to use, so it's more accurate. The power loss running the belt(s) and pulley(s) is probably not enough to make any substantial loss. Due to cooling system setup in dyno room, it wouldn't be practical to set up the belt system. We have the opportunity to test most of the engines in the cars after they leave our shop. For the most part, the "time-slips" from the cars go back and confirm the dyno results. We even go back past that and confirm the flow bench numbers also. Sort of "checks and balances" system. One other note, when you get involved in the initial firing on the dyno, there's less chance of any problems that would have to be taken care of in the vehicle later on. In other words, no oil leaks, no water leaks, no noises, no grief! We do a lot of resto-motors for a local shop and he has us "run-in" all his engines, just as a precaution. Thanks, Gary
