I recently switched my 87 Camaro L98 from TPI to Carb. The car is not a daily driver and I want to get as much out of the engine as possible. I have a little bit of money to spend and want to use the following set up. Can someone who has a desktop dyno or other program give me an estimate on horsepower?

Engine: L98 recently rebuilt with stock bottom end.

Heads: World Torquer S/R, 2.020"X1.600" valves, 76cc intake runners, 1.25" single spring.

Intake: Weiand X-celerator single plane, 2000-6000 RPM power band.

Carb: Holley 600cfm Double Pumper.

Cam: Crane Powermax adv. dur 284/292, dur @ .050" 222/230, .509/.528 lift, 112 LSA, power band 2500-6000RPM.

Trans: TH350 with kit.

Converter: B&M Holeshot 3000.

Gear: 3.73.

Thanks in advance for the help!!!

 

On desktop dyno 2000 I got the following numbers with 9:1 compresion:

with stock exhaust: 325hp @ 5500 rpm torq 346 @ 4000rpm

smalltube headers with mufflers:
366hp@ 5500 rp torq 395 @ 4500

The program isn't so specifiic that it differs from one single plane to another. THa cam numbers like lsa cant be adjusted either. So in reality you might get a bit more than this.

 

Sure they can, you need to enter the opening and closing events separately.

 

Thanks Tilstad,

I have most of the parts listed above from collecting parts over the years. I wanted to reuse them so that I could use the rest of the money I had saved up on painting my car. I figured somewhere around 340 hp, but wanted to have someone double check me.

Thanks again!
