The donor is a late 4th gen F-body piece. I don't care for the extra width of a 4th gen housing in a 3rd gen, so I'll be moving that factory Zexel Torsen diff and 3.42 gear set to a 3rd gen housing, along with the aluminum cover and LS rear disc brakes. I'll have to buy some new axles, as my '88 has 26 spline axles, and the 4th gen donor is a stronger 28 spline design. But those are Rock Auto pieces, as the last of the 3rd gens, '91-'92, also had 28 spline axles, and in (obviously) the 3rd gen width.
For me, it's a giant snowball. While the axle is out, that's the ideal time to install the Borla catback system I have. And of course, there's no need to add that to the stock cat, y-pipe and manifolds. So that means it's time to install the Ceramic coated SLP headers and dual cats. We all know those 33 year old exhaust manifold studs are not going to cooperate, so since I have them, that's the time to swap to the L30 Vortec heads. And if the top of the engine is apart, the GM/Crane roller cam and new intake make sense now too. Better water pump, rear main seal, and colder thermostat, lower temp fan switch, and host of other "while I'm in there" upgrades go in also. All the hoses are originals, so I'll have to make some date coded replacements. All that engine work means more fuel is needed, so with the axle and exhaust out, it time to drop that tank, clean and seal it, and upgrade the fuel pump and wiring. The axle gets aluminum control arms and Bilstein shocks as it goes back in, so I'll have to install the Koni front struts at the same time, as well as LS front brakes to balance the rears. And strut mounts too...those are still the originals and long since past their prime. There will probably be some mild lowering springs in that formula somewhere. The stock 700R4 probably comes out at this time to be rebuilt to handle a little more power, and a little higher stall converter will go in. I have a strut tower brace, wonder bar, and know which subframe connectors I want, so I might as well get them in now too and be done with it. It's a crazy bunch of work to take on all at once, so it will definitely be a long winter tear-down and rebuild, when the time comes.DynoDave

The whole "always a Cali car" probably helped significantly there.Gone but not forgotten: 1986 Chevrolet Camaro IROC-Z

Very true. I'd rather spend a little more and have a piece of mind than see what i've worked so hard just fall apart.Last edited by Pyramid_Head; April 12th, 2021, 11:29 PM.

Well, seems like this engine built has come to a hault again. Block has a crack, and my son dropped a piston, putting a nice dent at the top. At least i have some working 350 vortec heads... and a whole bunch of new parts.... just my luck...

It's obvious that i need to swap out that piston... i might upgrade to some flat tops. As for the block.... i dont know... It might still fly since it's only a surface crack that has to do with accessories, and not internal stuff. I may just send it out to a machinist and have it repaired. .... more $$$$$.... more nagging from the wifeLast edited by Pyramid_Head; April 20th, 2021, 09:51 PM.
