4" connectors and clamps wont be in for a while. Till then, duct tape is king
Im still trying to figure out how to run the intake tubing. 4" is excessively huge and every little bump or stud catches it. Plus the upper rad hose is flat out in the way

I didn't have any issues running my 4" intake tube over to the driver side fender area. The upper radiator hose touches a very very small part on the intake tubing, but the filter is picking so much cool air, and that combined with the speed that it is going through the tube, won't really allow the radiator hose to warm up the air. It was in the mid to high 40's today and I drove my car around literally for 4 hours and the IAT never went about 48*.

Drove in there
Goodbye LO3
Swap the pump
Drop the SBC
4th gen MAC mids are a no-no
And its in there
Fuel system
Prepping to build a new crossmember for better exhaust clearance. I can jack a house up with that thing
Whats up with this?
New crossmember and Y. 2.5 into 3" then LM1 catback
Sorting the cables and built a new steam line T. Upper rad hose is a 93-95 3.4L Fbody. Lower 90 F250 7.5L with a bunch trimmed off the ends
All done
Lots of room
Yessir

2000 LM7 longblock $200
Fbody trim was almost 3x the engine cost
98 Fbody 4L60E
Original 2.73 open drum axle, eventually Ill pull the 3.23 posi disk axle from my GTA and slide under there, but itll be a ways down the road
A new oil pump solved the no oil pressure issue. Sewing machine is still going strong unfortunately. Ill readjust the valvetrain and dump some Lucas in. Beyond that, all I can do is run 'er till she blows. Im going to look for another 01 or newer longblock to put in. This time with a warranty

Hey pocket. Great thread. I am getting everything together to drop a 6.0l, t-56 combo in my 85 iroc. I am wondering what you did for the radiator? Did you use the original radiator? I am asking because my radiator is leaking on the inlet tank. I have found a tank for it, but if i need to change the radiator, i will get a new one. The car has 34,000 miles on it. It does sit alot. Thanks for your help.
