Re: LS1 1991 Z28 Swap
The seats are a direct bolt in. I actually get allot of questions about the car, everyone thinks the seats and console are factory. Fits in great, its actually a direct bolt in also. The only thing I am lacking is a trim plate for the front of the firebird radio pod.

Re: LS1 1991 Z28 Swap
I agree that it looks factory especially being that they practically are I am just not a fan of the flow of it with the third gen dash. Are you planning to replace your dash as well? I see its got a lot of cracks in it.
I am gonna have to look around for 4th gen seats, thats official. What about the back seats?

Re: LS1 1991 Z28 Swap
I actually had a buddy, who is a wiring genius, give me a hand. The wiring itself took approximately 3 hours, with good schematics. Now if I had done it on my own, with the little electrical experience I have, it probably would have been at least 6 hours.

Re: LS1 1991 Z28 Swap
I didnt have to do anything to driverside firewall, I assume you mean the bulkhead connector. I used a Speartech wiring harness. Honestly, using anything else to wire in a harness, you would need to get the schematics from a factory service manual. You can find them on here just do a search.

Re: My LS1 Vs. 2001 Corvette video
Man I am DEAD SET on this swap. First I got to sell my lt1 t56, then my various tpi parts. Sell my 94 m6 z28, then pull my motor and tranny, sell it. Then find a t56/ls1 combo and get to work haha.
----------
One more thing. I have 2 t56's at my house. Both are from a 94. One is actually being used in a drivable z28. The other has been sitting in my room for months. Instead of selling the t56 that I have. Would it be worth keeping? Getting another bellhousing and ls1 and putting it all together? What do I need to make an lt1 t56 work with an ls1?

The ls1 T-56 has a larger inputshaft. If you sell one of the LT1 T-56's pm me with a price.

Re: LS1 1991 Z28 Swap
The clutch hydraulics are different since the LT1 is a pull clutch and LS1 is a push clutch. Also the front adapter plates are different.You can interchange them, but you have to change everything from the front adapter plate forward, including the input shaft. But behind that I belive they both are the same.

Re: LS1 1991 Z28 Swap
The ac compressor is in the factory location, I notched the K member. The strut tower brace is an Edelbrock, for a 1991 Camaro.
Re: LS1 1991 Z28 Swap
I was actually wanting to know about the K-memeber brace. Some cars had these metal triangular pieces on the 2 sides of the K-memeber. I think one side attaches to the k-memeber and other to the body.
You could order Spohn K-member with those on it.........but heard that there might be an issue of it hitting the LS1 AC comprossor.

Re: LS1 1991 Z28 Swap
Ahh those braces. I just took mine off and meant to replace it with something modded or fabbed up and never did. Drives just the same as before so no issues without it that I have noticed. I left the drivers side on though. I also have pretty major frame connectors on my car kind of half SSM and half Kenny Brown but they are welded in all throughout the underside so that might help stave off flexing issues.

Re: My LS1 Vs. 2001 Corvette video
I like the wheels on the car with the sides of the spokes black. I think the black on the car would look better if it were gloss and not flat. What exhaust is that? I really like the tone.

Re: LS1 1991 Z28 Swap
Very nice work bro! In the next year or so I will be attempting that same swap. Right now I have my built 355 and a T56 out of a 97 trans am. I love the six speed! Still didn't get my speedo working yet, to busy driving it!

Re: LS1 1991 Z28 Swap
Dude, drop the front tag, get some clear corner markers, new parking lights, new headlights, paint the wing, and the car would double (or possibly triple) in sweetness.

Re: My LS1 Vs. 2001 Corvette video
I think the black on top looks sinister. I've received allot of props on streetfire. It looked like poop with the clear coat coming off. I am of the mindset, go fast first then make it pretty. I dump alloted of cash on the swap, I am pacing myself. Besides, people really underestimate it as an old worn out TPI camaro....
I do however have another video, me racing a 2001 Corvette. I look pretty fast next to him, but once he learns to drive it, he has only had it for a few days, he should outrun me. If you guys have a Streetfire account, leave some comments on my videos.

Your dyno numbers look pretty consistant for a stock LS1. My first (97) C5 (stock) put down 313/332 rear hp/tq. But with Heads, Cam, LS6 Intake, Headers, and underdrive pully put down 430/400 rear hp/tq. @ 6500 rpms.
You should be able to get a lot more out of that LS1 then 285 rear hp too.
and for you guys talking about dynos.
a mustang dyno simulates load that's all. a dynojet can do the same thing with and eddycurrent...as well as a dynopack.
dynojets are calculate power off of inertia...spinning drums to measure power..but with an eddy current can be made to hold power...primarily it is best (all load dynos) for tuning. But I have seen plenty of 600+ rwhp cars tuned on a dynojet...with a MAF....and turn 11 sec and under in the 1/4.
the reason a dynojet works pretty good (with an eddycurrent) on a car like the C5 is that the car is very close to the drum weight of the dyno. There are two drums...each weighing 1600lbs...thus totalling 3200lbs. A C5 Z06 is 3150 and between couple and vert get to about 3350lbs. So it is almost one to one with respect to weight and is reliable.
mustang dynos do show about 8-10% less rear wheel power then a dynojet not using a eddycurrent.
Just curious what your setup put down for hp/tq numbers...what intake did you use (97=s LT1 right)?

Re: LS1 1991 Z28 Swap
I drove my car open manifold to an exhaust shop a few miles down the road. They made me a custom y pipe and mated it up to my exhaust. I will see if I can find a picture.

Re: My LS1 Vs. 2001 Corvette video
It has stock manifolds, with 3 inch pipe back to a two chambered flowmaster, single in with a single out and a single 3inch tip. I am adding a Borla intercooled round/slashed tip in a few days. Plus and exhaust cuttout. I will add a video after I do. I got it painted, the black is now gloss. The pics are above.
