Quite a bit of questions about LT1s I am about to trade a lifted Jeep Cherokee for a 93 Z28 with a 95 motor(m6). Its needs the opti distributer. I also have a gen 1 383 long block with a good set of high flowing heads (202 160s. 70cc i think. screw in studs guide plates and double valve springs) its also got a lunatti voo doo cam). Anyway, I was wondering if the lt1 fuel injection would fit on the gen 1 motor. The only thing I dont have for the gen 1 is the carb and distributer. I know LT1's are reverse cooling but I have a good H2O pump and all the brackets for the Gen 1.
Or, could I put my 383 a shortblock and use LT1 heads/intake?
Or, just see if someone wants to trade my 383 for a supercharger?
Or, just cam the LT1? There is a CC502 cam local for 100 bucks.
please keep in mind I am a poor poor poor college student.
I really miss my LS1 with a TSP MS4 I sold when I was laid off from work...
I will post pics tonight when I get the car. Its red with a black top. I already want to do a 98+dash swap...

The lt1 stuff will not work on a 1st gen block like you said lt1s are reverse cooling. If i were you fix the opti and do all the bolt ons depeneding on the miles heads and cam

Anyway, I was wondering if the lt1 fuel injection would fit on the gen 1 motor. Not without extensive and expensive modifications. Not worth the effort. The only thing I dont have for the gen 1 is the carb and distributer. I know LT1's are reverse cooling but I have a good H2O pump and all the brackets for the Gen 1. The LT1 block needs the LT1-specific water pump.
Or, could I put my 383 a shortblock and use LT1 heads/intake? Nope. The cooling passages are different, among other things.
Or, just see if someone wants to trade my 383 for a supercharger?
Or, just cam the LT1? There is a CC502 cam local for 100 bucks. The CC502 cam is a very small non-aggressive camshaft profile. I'd look into something more like the CC503.

Well, the miles on the motor are 105k. I just found out the heads were milled 20 and the intake was 10. I can get tuning here locally at some good shops. The guy also has a good opti still in a box he is throwing in. He said he has the 93 complete that was pulled for a wrist pin (supposedly fixed) that I could get if i traded my 383.

On a different note, The MS4 cam i used to have is a 239/242, .649"/.609" and an 111 LSA, is there a cam that is close to this size? I was really happy with the cam, and I would like to get one that was close to it. I know TSP gets their cams from Comp, so...?

TY thedon619. Any idea of a cam that would be aroud that size? I will probably try to get the spare LT1 and use those heads to put the valve springs, RR, lifters and P.rods on so when I do change it over I will have everything ready to go in.

Verdad Gallardo They is no cam the size of an ms4 for and lt1 other then a custom grind and youre looking at a lot of head work for that size cam and some serious vavle springs. Remember lt1 heads dont flow like ls1 head the cams are usually a lot less lift

hmmm...I went ahead and traded my Jeep...like I said, the heads have been milled 20 and the intake was milled 10. It has 3.73 gears. So, the CC503 cam is the cam I should go with? I will need the usual valve springs, lifters, pushrods and 1.5rr right? I really dont know anything about LT1s lol.

I just thought of another question, I have a wrecked 93 Z (hit a telephone pole dead center) and it has no motor trans k member or anything like that. Would a gen 1 motor be able to use LT1 motor mounts on an LT1 k member? I am thinking about stripping the car down and making it a full out race car. My gen 1 383 and a th 400. Seeing as how I wont be able to use it for the other LT1 camaro I have now!

So, guys I thought I would ask you a few more questions. I am having some problems with the spark on the car. I put in the new distributer and put on an aftermarket cap. I also put on a new coil. It would run for around 30 seconds then it would die. Then it wont start. I thought it was the fuel pump and I was going to replace the pump, but now I have no spark. I am thinking something is wrong with the coil, I pulled the plug off the coil and it wouldnt jump the spark from the coil to the wire. I will be replacing the fuel pump anyway, just because I have one around that works, and I want to eleminate any doubt that is one of the original problems.
I am not sure the computer from the 95's motor was changed with the motor into the 93. Is there any difference between the twos computer?
Any Ideas? I am ready to get rid of this and buy a M35 and bob it.

I will call the guy I got the car from tonight to double check if he did change the PCM or not. I do know that there is a MAF sensor on it. There is atleast 5 loose connections on the car where there are wires not clipped into anything. I want my Jeep back lol!
Any Idea on what would cause the a brand new coil to go out in about 2 weeks only being started once a week? The guy told me before I traded it that he took it to an electrical shop and they said that the distributer was the only thing wrong with the car. "They checked the car bumper to bumper"
