Here's a pic from the testing we did with you and GM motorsports on our SpinTron.



There's also an article in Race Engineering about our springs being in your engine.

I am surprised that has not been asked yet as the number is just average now. That would equate to around 515 rwhp? give or take? Still strong motor, but nothing to write home about.

Yeah, there's 416ci's, let alone a 427ci, with L92/L76 combos and smaller cams (in the 230's both sides) that are making 630 FWHP. Builder down here makes 680 FWHP with his 427ci's with small 230-ish cams.

So, I now know that the LS7 Head/Intake combo will make 36 more horsepower than the L92/L76 combo.

What duty cycle are you hitting with the injectors? What fuel pressure are you running? Is this on a stock fuel pump?

I am using 42#SVO injectors. But have no idea where to start on the Fuel pressure. Thanks.

Stock is 58# and I have tuned 3 LS7/L92 s with SVO 42s and they run ~82% which makes me also wonder the duty cycle on those 40s.

JUst a little food for thought. 640 fwhp on the Katech engine dyno equalled 551 on their Mustang chassis dyno through a 4.11 12 bolt.

I would say that ~520-530 rwhp on a mustang is pretty impressive...

Sounds like their mustang dyno numbers are like a dynojet numbers.
