Swapped heads cam exhaust - how much power

[EagleMark]

Paint marks are all but gone nowadays, the post color does not indicate anything.

Grab the number and look, there's lot's of differant information on how much they flow, we started a list and supposed to be correct for 13 PSI

Orange Black 61pph
Yellow Brown 65pph

You have plenty of fuel right now and need to adjust lower VE down. But installing the timing table that went with the motor Fast355 built would be first for big improvements. With 8 degree distributor setting figured into the ADX file you are running about 12 degrees advance WOT. And cruise about 18 so yes it would be low on power.

Now you have to be very careful with spark advance! You disabled a lot, did not account for 8 degree base setting. Have you checked at timing marks with light to match what ADX is showing?

Orange/black are 55pph pn 5235206

Orange/black are 55pph pn 5235206

This is from eaglemark's link

5235279 - White / Green - 50pph (overrated @ 55pph) - 5.0L / 305 Cars/Trucks

5235206 - Orange / Black - 61pph - 5.7L / 350 Cars/Trucks

Hmmm....all other resources say 55pph, dont even list 61's.

we've been there before. the 5235206 are 61pph. after my first mistake I made with injectors I always look up the flow rate in the bin for the vehicle I take the injectors out of.

The first list ever compiled at DIY EFI was wrong and spread across internet like gospel truth and now can never be fixed... if you look at a 1995 5.7L bin like $0D it says 61PPH

Ok...good to know.

[pima.1971]

OK. Changed it in the adx. I see what you mean. I appreciate you breaking it down like that. That was easy to follow.

On the scalar of initial timing adv it is set at 8.1* Is that not right?

No I did not check timing light and adx showing. But I can. It will be a several days before I can.

Yes that is correct for XDF. But in the ADX file it is set to 0 and has to be compensated for to read correctly.

X * 0.351563 + 0.000000
Change last number(offset) to initial advance of engine, for correct display.

Yours would need to be changed to X * 0.351563 + 8.100000

I think I reversed it in other thread and said it was less but it is more, but with all the compensaters and you zeroed out some what is the timing really? That is my point!
