I finally finished the swap. It's amazing how uncluttered and clean my engine bay is now. I think I could change injectors in ~15 min. I just took it for a spin around the block with only one problem...I'm having a hell of a time getting the water neck to t-stat housing to stop leaking. I'm hooking it up to the scanner tomorrow and start the prom burning process. Stay tuned for performance results.

 

Very nice. They look good red. Where did you get that fancy duct work (boot & pipe)? Is that an LT1 throttle body or TPI?

I ordered two stainless elbows and found some stainless pipe at work, then had a guy in the shop weld it up for me. I ordered the red turbo hose connections from hose techniques.com to connect the MAF. I went ahead and had him cut me another piece of stainless to take the place of the MAF when I convert to MAP. The throttle body is a 58mm TPI Edlebrock that I was using on my LTR setup.

 

Looks great! How did you paint the intake? I hope mine looks that good when I'm done. :hail:

Have you noticed any difference on the "butt dyno"?
I also have the ZZ4 motor, what were your times before you did the swap?

 

First thing I did when I got the intake was a thorough cleaning, then a couple hours sanding and polishing out the top fins. I taped off the fins and the mating surfaces (TB, head), then painted with hi temp paint.

I've only driven it a 1/2 mile, just to make sure I had the throttle and TV cables working right, so I didn't run it hard. I guess I can tell a little loss in torque. Geez, this motor has always been unbelievable on the low end, so as long as I've gained it on top I don't care...maybe I can launch better now. My best g-tech run before the swap was 13.25 @108. I won't be doing any WOT runs until I get all the part throttle stuff tuned in. That could take 10 chip revisions. After a few scans and prom burns tonight I will definately have an opinion of the performance potential. If I find out I'm maxing the MAF to 255 gps at a low rpm, I'm going to go ahead and do the swap to MAP and 730 ECM right away, before I invest months into tuning this thing.

 

How do u get a LT1 intake to fit on, what is that site that tells u how? also, did u see any different numbers in hp from the intake?thanks

 

I can help with the first part of that question. The site is http://www.lt1intake.com/

Where did you get the fuel lines made?? I have checked with EVERYBODY here in Des Moines and they don't have the fittings!! I am currently finishing the LT1 intake swap and within a month I will have the new engine and trans installed as long as the money keeps flowing.

 

I purchased the fuel lines from John Millican.
