I will throw 406/360 SAE out there. Stock shortblock cars don't normally see over 360rwtq unless the dyno is showing a flash from a converter.

 

I say if its a good day.....406hp and 373tq

 

Man, Oh man oh man. This doesn't look good...
390.2rwhp 357.5 rwtq.
The car went to 6.2k rpm. The AFR was between 13.0-13.5 the entire run.
This doesn't make sense.....All I did was fix the blown head gasket, have the pcm retuned, and changed to a 52mm tb. The check engine light has always been on, but never hurt performance. My last dyno was 399 rwhp and about 369 rwtq.
I came home heart broken wondering what the hell went wrong. Well, I have Comp R lifters and when me and friends adjusted the valves, we went by the GM manual and just turned the crank.
I went outside tore off the valve covers and adjusted the rockers with the car running, put everything back together and went for a test drive.
The car pulled like mad and I even chirped 3rd gear (not barked--but chirped). I felt a huge difference and I knew the car was where it needed to be.
I called the dyno up and asked could I come back since I readjusted the valves and he said yes, come on, but I'll have to charge you again. I said OK I'm on my way. End result was.....
403.5 rwhp 373.7 rwtq. Standard

Now who do I need to mail this $20 to or do I get to keep it myself, LOL

What about SAE? Those are the numbers that most people go by.

 

yea, those R lifters are picky about adjustment. If they are a lil off, the #'s always look bad.

Great #'s once they were adjusted properly though.

What where the SAE #'s?

lol, if i had posted a guesstimate earlier, i would go back and edit my guess so that it reads what you posted.

 

Hey guys,
I'll have to get the SAE #s next week. I was sooo glad to see 400 something that it just slipped my mind and I was trying to get the hell out of there before the dyno owner could say that there was a spike or malfunction at the end of the run that caused the numbers to be more than what it should have been, LOL
Blklt1 z28....It appears that you came closest to the actual numbers, but before I confirm that, I'd better get those SAE #s first.
BIG Thanks to Mr. Lloyd and to all that had a part in this project of mine over the years. The knowledge of the people on this board was a tremendous help to me. Keep up the good work
Take Care and I'll post those sae # as soon as I get them.

Correct me if I'm wrong....
I have this other sheet that gives a breakdown of
TIME/RPM/POWER/TORQUE Absolute barametric pressure: 29.68 in.hg.
Vapor pressure: 0.15in.hg. Intake air temperature: 78.8*f Gear Ratio: 51.24 RPM/mph Correction Factor: 1.01 STD.
If this sheet is the SAE correction factor, then my numbers are...
400 rwhp/ 372.7 rwtq. Here again, this in on the other sheet that he printed out for me. If this is not correct, then I'll get the SAE printout next week.
Either way it goes, I'm happy.

I was wrong in the above post. According to a formula (standard rwhp & torque #s multiplied by 0.96=SAE) given to me by a fellow board member (truedualws6), my approximate SAE #s are
387rwhp/359rwtq SAE.......

-Tim....But here again, I'll get the printout next week.

 

OFFICIAL RESULTS....
403.5rwhp/373.7rwtq STD....393.7rwhp/364.6rwtq SAE

Blklt1z28, Its seems that you won unless someone can prove otherwise, LOL
PM me and I'll get your info.

Thanks Everyone.

What kind of head gaskets did you use? I'm gonna be buying a whole new round of gaskets/bolts when I get my heads/cam swap. Were you using stock, and were they sealed correctly?

 

409/378 Sae

 

Blind527,
I used the Felpro 1074s if I remember correctly. I would have gone back to Felpro '95 Impalla Gaskets (.026" thick), but my heads had to be shaved and I was afraid my compression would be too high if I used them. I think everything has sealed pretty good. I used the ARP head/intake bolts.
Good luck

-Tim

 

24 Horsepower.....and 56 pounds of torque.....some of the head bolts aren;t down tight enough and the heads going to blow of the block before you hit 2 grand.....

HAHAHAHa


If I am right though...I definatly want me 20 bucks
