Hey all. Just looking for some tips on a swap that I am looking into.
*DISCLAIMER*
I do not want to swap in an LS engine, so don't tell me that is a better idea
I realize this is a very difficult swap. I'm ready for that.
I have a roughly 400 horsepower Pontiac 400 that I rebuilt last year that is just sitting under a bench now. I am looking at putting it into my 1995 Pontiac Trans Am. The LT1 and T56 are still in the Trans am for now, they will be out soon. I was just looking for some answers as I know this is not a common swap. I have come up with a list of questions to ask and would greatly appreciate anyone that can offer their assistance.
1: Does anyone know the exact measurement from the top of the k-member to the bottom of the hood by the cowl? I am designing my own plenum style EFI intake for the Pontiac engine and need to know how much room I have to work with.
2: Does the optispark contain both the cam and crank sensors for the LT1? I am trying to utilize and adapt the LT1's engine management system to the 400 and was curious if these two sensors were in that bastard. I am planning on going with a cam sensor and crank trigger for the 400.
3: What is the lb/hr rating on factory LT injectors?
That should be about it. I have most of it figured out. I know that Butler Performance built a 2000 Firebird for Pontiac for SEMA with a Pontiac 400 under the hood. This has been quite challenging as I can only find one vague picture of it under the hood, but I was raised Pure Pontiac and would like to get a 400 into my 4th gen, no matter how hard. I've already figured out how to make the T56 work with the engine, just need some help with the electrical system and such. Again, I appreciate any help that anyone can offer.

I'm pretty sure as long as I know the parameters of the engine and where I want everything set, a good tuning person can remap everything to work for any engine.
