Aluminum bearings ? WTF
I think anyone would know forged pistons are obvious & a roller valvetrain to for that matter. Eagle rods? kinda general remark, dontcha think? I mean Eagle is an ok rod...& they do make a low cost standerd issue Ibeam rod & also a Hbeam. Oh well, those comments were from the guy who says he hates Chevy guys.

The racingjunk ad states dyno'd with 107 octane race gas

They ran 107 in it, but on 10.8 compression and aluminum heads, that is easily a pump gas motor. My dad has a 383 with 11:1 compression and aluminum heads that has never seen more than 93 octane and dynoed at 444 RWHP.

I never stated it would not run on pump gas. But the dyno sheets are a proven 600 hp on race gas. You drop that to 93 octane and you are going to lose a decent number in the power department. On 93 I would say that is getting close to the 444 rwhp you are seeing in your father's engine. Run race fuel and you will see an improvment. As stated earlier in the thread 500hp/na is quite reasonable but add another 100hp and that goal is much farther than it seems

Ok, I see what you were saying. You are right, race fuel will add a little more hp due being better quality and having a slightly higher oxygen content. I have seen dyno tests on pump gas motors with 93 and race fuel, and on race fuel, and the motor gained around 20 hp. So that motor probably has closer to 570-580.

here is what it really takes: http://www.musclemotorsports.com/streeten.html its available in a 600 Hp pump gas version or a 750 race gas version (many of the parts are used winston cup goodies- hence the low price) . in a home build i think your money is better spent adding forced induction. stroking a 350 to a 383 only adds 33 ci, at 1.5 Hp per ci you are only talking 50 Hp, IF and only if your heads, intake, carb and exhaust flow the additional 14% otherwise youll only increase the output in the lower rpm range, and 14% additional torque is a good thing, but it doestn nessecarily translate to 14% more top end Hp.
here is a run down of the parts in the 600Hp build, try that on that budget (12-14000): 355 – 360 cubic inches Compression ratio 10:1 runs on “pump” gas Block: Chevy BowTie, 4 Bolt Mains, Splayed Billet Caps Pistons: Forged Aluminum Alloy, J&E or equal, Bore 4.125 Crank: Billet Sonny Bryant, Stroke 3.335, 37-45 lbs. 2.0 or 2.1 rod journals Rods: Carrillo or Lentz 6.20” H beam. Carr Bolts ATI Balancer Heads: 18 Deg. CNC Ported Aluminum Chevy Cylinder Heads w/2.150 Titanium Intake Valves, 1.6000 St.St. exhaust valves, Comp Cams triple valve springs, Titanium retainers and keys, Copper Berylium Valve Seats, Heads Flow 330 cfm @ .700 lift.

Race gas does not make more power, it ALLOWS you to make more power (meaning higher compression, more timing, boost, nitrous, etc...) If you have a 9:1 engine that runs fine on 89 octane and you fill it up with race fuel, the car will not be any faster. This is a common mis-understanding. Now if we are talking nitro that is different but, race gas does not make more power just by filling up your tank with it.

Camaroman, I understand what you are saying about race fuel allowing you to make more hp, and not adding hp, but I have seen tests with pump gas motors that did not need race fuel (9.9:1 with aluminum heads) that gained 15-20 hp running 114 octane over 93 octane pump gas. The people who did the test claimed that the extra hp was due to the race fuel having a slightly higher oxygen content and fewer power robbing additives than the pump gas. Most gas from the pump has emission additives that will slightly hurt performance.

I think I personaly will take the advice and build it for 500-525hp N/a Ill just top it off with a mild nitrous kit....that way I can call it a "grocery getter" lol Quote:
hmmm, he just blew that guy off because he didnt want to build it the way he wanted to, thats what it looks like to me, and wow did that guy charge him! if someone paid me 3,000$ for a stock rebuild you can bet if I didnt do anything Id make it pretty! ...lol Last edited by 2wld4u; 05-08-2004 at 08:58 PM.

Race gas will make a power difference this is not a misconception. When my engine was dyno'd on 93 octane it had 431 hp and stepped up to sunoco 103 and had 448 hp
