Going to Dyno the car tomorrow, any guesses on what she's pushin?

[5-oh stang]

The mods to the car are as followed:
'90 model 351W bored .030 over Kieth Black flat tops with 2 valve reliefs
AFR 185 CNC'ed heads
Comp cams Xtreme energy 282
Edelbrock performer rpm intake
750 holley dp holley mechanical fuel pump
Stock 5-oh headers with home made pipe connecting them to a shorty Mac Pro Chamber H-pipe, Mac mufflers and 2.5 inch tailpipe.
Timing set at 10* 34* total timing All duraspark ignition
T-5 Tranny
373 gears

Any guesses on what she will put down?? I know the stock type headers are choking it to death. But any guesses welcome Thanks

Over 350rwhp

If it runs right and that's a good cam (i have no idea if it is) it should be 400rwhp.

If it's only 350rwhp, i'd be pissed.

A lot of that will depend on how well your carb is tuned. It seems that this becoming a lost art and most people lack sufficient knowledge to properly jet and tune a carb for an engine.

If the carb is good, I'm betting 330hp to the rear wheels using the stock headers.

I'm also thinking 350ish rwhp with the stock header.... 1 1/2 inch primaries and a 351 = teh loSe!!

 

[cmb91LX]

285HP
285TQ

Let us know how it turns out...

 

[N8Miller]

345 rwhp

Well what a big let down!! The guy at the performance shop had trouble early on today trying to burn a chip for another mustang and they are not going to be able to get to me 2 day I can't do it next weekend cause my buddy has a big race going on, so looks like it will be 2 weeks before i get to go to the dyno, and by then i will have 1-3/4 long tubes on it, so we wont get any before and after comparisons. What do u guys think she will do with headers on. I will keep you all posted as soon as i get some numbers!!!!
