73 Corvette LQ4/TH400 Hi this is our 1973 Corvette. A little about the car my parents originally won this car from Wendys back in 2004 I want to say. Well anyway they drove it for a few year replacing only little things water pump, radiator, and normal maintenance untill the other day when it gave out. Personally the 190hp was never enough anyway so we decided to go with an LQ4/th400 swap. Here is the car today...
We plan on picking the motor up this friday and ill be pulling the old one out prob tomorrow so ill post pics.
Advice/Imput welcome

How so? I thought there was a difference in the truck injectors vs the LS1 injectors going into the LS1 intake. Could you explain more please?

I used a cleaned up truck harness on both my swaps. Biggest problem for the vette is finding a mounting location. There was not enough wire to mount it up behind the passenger wheel well, so I made a metal box and mounted it to the passenger angled footwell sction.

Thanks for the link looks good. I test fit the engine the other day with the truck intake on and its prob 2.5 - 3 inch's to tall I knew this befor I did it but I was bored. I bought a ls1 intake manifold with the rails injectors and throttle body for 250.00. off ebay waiting on it now. The stock truck header fits on the driver side fine but is just a little to tight on the pass. side so im looking for some headers that fit mayve Z06 one idk.

I dont use a prepump filter just the sock in tank and the c5 filter.I also used the 255 and since i dont have baffles in the tank i came close to running out one night and burnt pump up.SOOO im modifying my tank and probably going back with same pump.
