Wow this build looks great! Can't wait to see it finished. Keep up the good work! I was disappointed you didnt keep the procharger because I would be interested in possibly putting one on my car. With that said I could never criticize anyone for wanting twins over a p1sc!

Thanks, As far as the procharger kit goes with what i had mocked up it was not hard to fit the headunit with the hinson radiator, i did not even touch the mounting ears i just moved the radiator to the furthest forward mounting position on the underside of the frame rails.  It could easily be made to fit if you just had the blower headunit, a j-bracket with hardward and a crank pulley standoff (since thats all youll really be using from the kit).
If you have some time to play with it, anyone with basic skills could tackle a large part of the install.

Are you sure? From the pics it looks like you had 4" cearance before fans and still needed to make the 90 degree transition of the head unit? I thought for sure I would need to change radiator set ups.

I think by modifying the mounting tabs on the Hinson radiator to increase the angle there by increasing the clearance down low by the blower it would clear very well.  I did not get that far before i decided that 550-600 whp was less than i wanted for this particular car.  If a compromise needed to be made the fan could be mounted offset with a low profile shroud to allow more clearance on the driver side.  There was a low profile 90 called a cobra head elbow that do well for the given space. http://intakehoses.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=CHEW
I have no doubt that it would fit and fit well with these modifications.

So a nice gentleman from the machine shop rolled my short block back over to me yesterday.  I did not have time to touch it then but my boss gave me a day off so I could come down to the shop and work on my own stuff  :)


Here are some pictures of the short block












A little progress (would have been more but I didnt order a few needed gaskets and forgot to bring a few parts from my house.















And pictures of things to come...






Really would like to get my cam and finish buttoning up the longblock.  More to come.

Put my pan on:



Mocking up the intake manifold for kicks:









After pulling the engine off its stand and bolting on the flexplate I popped the trans back on it and put the engine in the car.

the IM is ~6.25" from the valley cover to the highest point.  Fuel rails sit up an additional .25" above the IM

what an amazing build and glad you are taking the time to do everything once and not 3 or four times because you just wanted to get it done and would touch it up later

My browser is freaking out and wont let me quote, Thanks for the nice words Skull.  I'm sure i wont be happy with it no matter how meticulous i am the first go round but i'm giving it the ol' college try.


Zbrown: While I dont want to get ahead of myself without some solid measurements I think its possible.


From what i can find on the interweb the fast102 intake is ~8" from valley to tallest point. Knowing thats not easy to package i take comfort in the fact mine is almost 2" more shallow.  Depending how i end up throttle body placement wise given my intake who knows?


FWIW this intake fits on vets without modification.
