Finally got the new engine running and broke in today. Here is a video right after the 30 minute break-in. Will post video of initial startup later.

Sounds great and looks amazing! What ET goal are you going for? I thought you said before the other engine went that you didn't want to have to put a bar in this car? Keep up the great work!

Yeah, I didn't want to put the bar in but... I don't know what to expect for times, as long as it's not slower than my old SI setup. Just from the short break-in run doesn't feel like it will be slower. I'd be happy with low to mid 11's.

How did you get the hooker headers collectors up so high? Mine on a stock ride height are almost scraping the ground...

I don't know, I just installed them. The cutout is the lowest point of the exhaust.

Mine are way lower. I have stock springs and I'm too scared to lower it!

I went one time to log some data for WOT tuning. Not a good day, three runs. The posi gave out first run resulting in 1.9 60ft times, trans was slipping in 3rd, DA was high, and was pulling 3-4 degrees of timing because injectors are too small. Ran a best of 11.6 @118. I think after I get all bugs worked out should be a real low 11 maybe a 10.9 in perfect conditions @ around 121. Just put a new Eaton posi in and going to work on some 60ft times since trans is done on top end one more time before season ends so I can hit hard next year.

^^^ wow I would be happy with just the 11.6 what size injectors are you running? I wonder if I should have went bigger Im running 36lb ford injectors. Im curious cause we have very similar setups with the exact same cam. But 11.6 would be just quicker than what I was shooting for.
