Do you think I should put a startup tune in it?

If you did not change the fuel system than it should start up fine with your existing calibration.

Correction: This motor has the MM Race. My previous MM Mid never had any fluid in it, but this motor will probably move more fluids.

No, I haven't make any fuel system changes for this build, yet. So, that makes perfect sense to me too Mike

We cranked it and let it idle for a while. Gave it some throttle two or three times. The log looked great. Trims were predictably a little rich. Logging some street data tomorrow.

I need suggestions on how improve my line and routing on the MM/valve cover line. Maybe a metal one like stock?

The car now has a mild road tune and will dyno next week. This time, I'll adjust the tune while on the dyno. I didn't do that last year. Just drove it on, twisted it, and drove it off.

I found an LPE BBFP for $800. E85 here I come...

Nope you’re not lol. You’ll need big injectors to run with that pump to run E85. Our power levels are similar, am running +52 injectors, and I can only run E50 FYI…

Yeah, I know 65+ and larger fuel lines and a flex fuel kit and God knows what else is required. The injectors are like 4k retail but people are always selling such stuff used for a lot less.

With inlet filter and 2.625 pulley = 1116hp/ 1063tq, on 100 oct.

The 1116 pull made 18.7# boost pressure, within a # or two of the previous motor.

The hpfp does not appear to be working very hard.

The perforated K&N air filter made the same horsepower as the Bellmouth.

The 3" upper made over 100hp less than the 2.625. It doesn't have enough blower now.

Timing advance = 22 degrees (!)

Before, I had more blower than motor. Now, I've got more motor than blower.

I'm not sure it has enough cam now either.

Those great numbers! Hooking will be your challenge now! If it hooks you will be in the 8's easily! Very nice!
