Default My turbo 4.8l 87 IROC build

well i got the chance to buy my old car back. i built this car back in like 04-05 and sold it for $5,500, bought it back a week ago not running but got it running for $700. absolutely love this car and drives soo much nicer then my 91. decided to go turbo 4.8l and hopefully t56. the plan is to completely shave the enigne bay clean and fill all holes and whatever. just picked up a 4.8l for $200 now to get the rest.

how it used to look:

already tearing it apart. man the coolant was as black as used oil and was hardly in any of the coolant lines. they ran a cheap little tranny cooler and there was no fluid goin through that. anyways heres some pics of the tear down process and the 4.8l i just got.

might i ask why you went with this elbow? i know the ones at 6061 are alot better than the edelbrock ultra low profile one which doesnt flow. seen cars pick up power from switching elbows. be like running a n/a 454, big cam, fast 102 and a stock maf. the ultra low just doesnt flow.
