Oh, Ok, sorry I didnt know.

You can go with the POL ( I did) means you can have the motor set back or forward. They would be fine with long tubes, although I have shorties. ECE has a good product also that I dont think are adjustable though.

Also you would possibly need a trans crossmember, unless you are using your stock 3speed. you can put the motor in with the 3speed tranny and you can use your stock 3speed cross member and mount. There I would suggest the POL perches.

Stock perches can be used, several guys have, makes the pan sit lower though.

I'm using the stock perches and mounts, with adapter plates. It sets the engine almost into the firewall, so I fabbed it so the perches sit about 2.5" forward (where the "front" holes on the frame are). The engine sits fairly low, with the pan and xmember being almost level to each other. This is an lq4 so it stands a bit taller than the ls manifold.

Do those POL bolt up to the stock holes

[Clyde65]

Yes, they will. The POL ones mount to either front or rear holes. The CPP ones will ONLY mount to the front holes.

ECE ( Early Classic Ent) has one that is similar to the 73-87 ( I think) perch, it will also work.

So did you redo your own harness or did you buy a plug n play, iv'e been trying to get a hold of Nelson Performance to see how much there harness is but can't seem to get a hold of themany suggestions on where to get one and at what price

[Clyde65]

Nelson has a great product, I had a performance tune done by them, great job. I do think their harness is a little too high. I would go with these guys, many good reveiws from here on them.

BTW, did you get the stock harness and the DBW pedal, PCM and all that from donor vehicle?

I had wait4me performance do mine, it is ugly but works, at least until I can afford the LT1 harness it works.

[BIG D 85 gmc]

then i would need to get a msd box for the coils right, or would the harness take care of that

[Clyde65]

their harness will have everything you need, all you will need to "hook up" is three wires I believe, maybe four. If your PCM is tuned, then hook up the wires and it will start.
