Re: Lt1 swap!

I have it up and running. Due to a phone mishap I lost all the pics I took while putting it in. I'll get some fresh pics today. It needs a better fuel pump which I plan to do today. It has more power at 1/2 throttle than the old tbi motor had. I'm having a chip burned for the ecm so I can get the most out of the tbi setup I'm running. I may even take the 4l60e out and replace it with a cable operated 700r4 and run a 4-barrel on it. The motor has the gmpp spreadbore manifold on it. The tbi will never be quite enough for the rpm this motor will spin. I happened upon a set of lt4 heads so things might get interesting
