I have an EFI'd '95 LT1 in my car... I love it, but the LT1 platform doesn't have the power potential of the LSX platform. I have an LS1 waiting in the shop for me to get the funds together.

I thinking about installing a mid 90s MPFI 318 into my old 81 Dodge----does that count???
I have the engine---need the right bellhousing for my trans now.

I've been thinking of trying one on the crate engine in my sig (Eelbrock 435 hp crate). I have been thinking about it for some time but the paperwork from edelbrock states not to do it but doesn't explain why. One thing stoping me is the cost, about 3k for a complete system from them, and I'm wondering why they say in all the paperwork not too. Currently it has an 800 Thunder Series AVS so I don't see what the problem is but before I jump into a setup I'm going to need to do some more research and save $$$ so it's going to be a while....

I have a TPI Engine from a 92 Camaro I have considered installing in my Chevelle. I'm just not really interested in the whole "Prom" burning thing.Now if I could find some other way to control the TPI that was affordable,I really like how well it works and I think it looks pretty cool.

I've got a buddy that runs a TBI on a first gen camaro with a dart smallblock. He controls the TBI and a 6-AL2 box with his laptop. It is one of the sickest things I have ever seen, and that car HAULS. Solid cam with 300-something duration and .600-something lift. It HAULS.

I have a Ram Air 502 EFI Crate Engine for mine. I haven't been able to talk to someone that has experience with this engine yet. I heard mixed opinions about it. Runs great with awesome response. Not sure about the MPG yet with the 700R4 tranny and Ford 9" with 370 gears. Haven't got it on the road yet. Some people like the lap top fine tuning options of other EFI's. I'm not sure how much, if any, fine tuning change capabilities mine has either.

My bud's car is all custom, home built, with a throttle body off a ford pickup, a fabricated intake box, seamless 316 tubing (1/2") all the way from the electric pump and aluminum cell, etc. The MSD box is on the kick panel on the passenger side, and has a place to just plug in with the laptop. He has taken out quite a few really hot turbo ricers with that thing.

I have been planning an EFI set-up since the late nineties, and now that my El Camino is running again I am doing the research and I'll start putting the pieces together for a factory TPI conversion for mt ZZ4.

I highly recommend the swap manuals from Jags that Run (http://www.jagsthatrun.com/).

Derek isnt that lt-one equipped with a multi-sequential FI system and opti-spark? But your right about the HP potential. I doubt if one could pull 350 HP with all the bells and whistles.

Grumpy, if you are talking EFI'ing a first or second generation small block , in my opinion the Tuned Port Injection is the way to go .... and they look so damn nice.

I doubt if one could pull 350 HP with all the bells and whistles.That's correct... on a stock bottom-end, about 425hp at the crank is the limit while still retaining some street-manners. As much as I'd love to have 425hp right now, I know I'll love 550+hp even more later. ;)

LS1 and 6-speed are sitting on the floor in the garage... still need to collect parts. I have the headers and the engine mounts, but that's it. I do plan to have some work done on it before I put it in though... Heads/Cam for sure, maybe more. I really want >500hp.

Yeah, I got a six speed (zf) in my '93 vette. Factory numbers puts it right at 300 hp. I put a chip in it and increased to about 330 by just having it run cool (185 deg instead of 220) but in 96 GM put roller rockers and more agressive cam in the vette and raised the compression from ten/half to ten/three quarters and called it a lt4 .... still only put out about 330 after all the improvements.

I cant imagine getting big HP (like 425) without going with spray!

But the lt-1, in my opinion, is still a great engine once the overheating issues are dealt with

Lloyd Elliott is the LT1-guru, well known for head & cam packages that make very impressive power... just not as impressive as what's achievable with an LSX. ;)

Didnt notice this post but if still looking I got the Edelbrock pro flo system.Wasnt cheep and at the time was bouncing between a blower or efi.Glad I picked efi because it alway runs the same no matter the weather.

I am still considering the Fast EZ system. I like that its all inclusive and handles up to 600HP.

I also have a '95 LT1 in my Skylark. Car is still in the build process though. Would have loved to go the LS route but it exceeded my budget. :(

My 79 El Camino (GMC Sprint) originally had a V6 and a 4 speed saginaw but I swapped the 6 and the saginaw for a L98 TPI with 5 speed out of a 3rd gen Camaro. Everything almost bolted in and the only thing I had to do was come up with a throttle cable and I installed electric fans with Bosch relays. The computer fit up under the dash by the HVAC and I didn't have to modify much. I did end up with a cowl induction hood and Monte Carlo SS interior. My car was a factory bench with no console and it had this little plastic hump on the floor. Best turn key car I ever sold. Wish I still had it but it was either that or the 70 Chevelle

I have the Edelbrock pro-flow EFI to put on my 383, got it used on E-bay for about 1100.00. I hope to get the car running in summer 2012. We'll see... time and money, not enough of either. Doing lot more than the engine to the car.

I installed Howell EFI(TBI) (cost about 1200)on my 6 cyl 78 Jeep CJ7. works very well, has an odd issue when warm sometimes trying to go uphill at speed. Never has problems when crawling on the trail, I like it much more than with the carb.
