Engine Swap #2
Re: Engine Swap #2
In order to run the ZR1 cam a different 3bolt cam sprocket is needed. On the LM7 the cam sensor reads off a reluctor wheel built on the camshaft. The ZR1 reads off a reluctor on the cam sprocket with the sensor on the timing cover. The new cover and sensor were only $75. The timing set I was going to replace anyway was the same cost as the LM7. GM parts are ridiculously cheap.

It would be a lot more expensive. I don't know if it would be easier. I wouldn't consider anything I have done so far to be difficult, just time consuming.
Re: Engine Swap #2
I installed the transmission with the adapter bracket I made for the 4G63 swap and mated the engine to the transmission with zero clearance issues. The engine sits forward more than I had originally intended but is in about the same position as the original V6. The F body headers are going to work too. The GTO oil pan will work with the engine in this position.

I'm sure that TH350 was a contributing factor in that as well.
Re: Engine Swap #2
Long time since I posted anything on this swap. The turbo part of the swap is on hold for now, I'll go into detail on that part later. I'm finishing up the wiring part of the swap this week. All the mechanical stuff is done except for the alternator bracket. The bracket should only take a few hours to complete now that I have the alternator in the right position. I moved the battery to the trunk. The overflow tank is going in the original battery location. The exhaust exits on each side of the front bumper. Hopefully it's not too loud with the baffles installed. Should be running in a few days if I don't run into any problems. I also am installing a gauge cluster from an 02 Z28. It's plug and play with the warren ECU with the addition of the Dakota Digital VSS I installed on the TH350. The only thing that will require modification is the fuel level sensor. The signal is inverted compared to a Chevy unit. I have a few ideas on how to correct it.
