Ive never had problems with a unilite distributor
had one in my camaro for 20 years with no problems.
Now my MSD6AL box fried twice so far.
I tried talking him into running alcohol but he wants to run gas for awhile.
(he wasnt too impressed with using twice as much alcohol than gas)

I'll give you a good example. I had 11 lbs on my SBC with 1.75" primary Hookers. Stepped up to hand built 2" to 3.5" headers and boost pressure dropped to 8 lbs which allowed me to raise it back up and run 1:1. THe headers reduced restriction.

i personally do not like the uni-light distributers.

I use a 6BTM with great results. Uni-Light? There's a reason they're referred to as Uni-Dark.

That's an understatement! Hmmm, two radiators, two water pumps, and three fans, just for the pleasure of driving on the street.

You've got some great advice here. When I built mine I had a close friend guide me along, but I still had to learn as I went. Good luck and we look forward to those videos!

WoW!!, looks great in the photo's.
I don't know but what i would also want to add is a front crank bearing support. On the second pass down the 1/8 mile i spit the harmonic balancer and the lower pulley off at about 500 ft. out, but i am running a 1471 full blown alcohol and about 30lbs boost i also had to double key the crank.
That's probably apples and oranges compared to a street driven blower though.
But it definately looks good to the eye.

Zip.
