I just had my car dynoed for the first time. Mods are in my sig but, in general, I have an E cam with GT40 iron heads and cobra intake. I bought the heads used from Stangnet a few years ago and was told at the time they were ported.

276 rwhp/313.8 ft-lbs torque

The A/f is rich. It fluctuated around 11.5. This could be because I run the ACT sensor in the fenderwell. I have the PIH kit with A9L computer. The cobra lower doesn't have the tap in the #1 lower intake for the ACT sensor.

sounds like good numbers! Get a better cam and you might find some more power, but still looks good.

Those are good numbers for iron heads and an e-cam. My friends couldn't break 300rwtq with GT-40 heads and Crane/Comp cams.

I think those numbers are good for your car. They are on par with other similiar combos. Lean it out some and you may find a few more ponies too.

Wow those are nice numbers for your set up. I may need to buy my brother's iron GT-40 heads and his E303 cam.

Are you running stock injectors? Only reason I ask is because I just bought a PRo M MAF calibrated for 19's and I wanted to know how much power the stock injectors can support. thanks,

I have 24lbers with a 76 C&L MAF, 190 lph fuel pump and afpr which I guess I'll start playing with to lean it out a little.

Those are good numbers....I have damn near the same set-up...I opted to stay with 19 vs swapping 24s...Makes me think I left some ponies on the table??? your like 14 Hp more than I....Oh well...add them to the Winter list... at the time I didn't feel like sending my Pro 77 back for recal...

So how much does it cost to recal the Pro M MAF's? I'd like to stay with my 19's for a while but I know someday I'll need to upgrade.

It was 115.00 shipped for my Pro-77....

My AFR on my last dyno was still sweet...the thinking was the AFR will dictate when your maxxing the 19s..I went with that thought...
Was also leary of EEC issues as I still run the stock computer...Sometimes its a crap shoot with SN95s....

Those numbers are VERY respectable for iron heads and an E cam. Sounds like the combo is a good match. You can always try a Pro M Optimizer to lean out the mixture.
I will swapping in the PIH kit next month and just ordered a Crane Hi6 ignition. Where did you mount the ignition box? Any tips on the install? Thanks
