Hi, I am a new member. I worked for GM for 37 years, the last 25 in the vehicle dev group. I was fortunate enough to have worked on the 73 Eldo pace car, the 93 Allante pace car, and the 02-03 Seville LeMans pace cars. I was the lead development engineer on the Allante and the 98 Seville. I have a Catera with a 7L (427) C5R engine and a Camaro 6 spd that was built by John Lingenfelter Performance engineering. I purchased the car from an enthusiast friend of mine that had the car built. I have started an Album under Catera V. I look forward to an interesting time with all of you.-Fred

Wow, people on here always wondered if you could put a V8 in, and it is possible... just most of us dont have the money to do it! Thats amazing, how did they fit a 7+ litre V8 into the engine bay!? I know they can do 5.7's but wow. :bonkers:


As i see also, you have a nice history at GM / Cadillac... very cool and im honored to meet you.


Thankyou for joining Cadillac Forums!!! We have many SeVille and Allante members also that may benefit from your expertise!!

The 7L is LS1 based so it is the same size as the 5.7. It is still a very tight fit because the Catera/Omega is 2 inches narrower than the GTO/Holden even though they are based on the same platform. This is a very difficult conversion because of electrical interfaces that must be delt with. Fred

Ahh yes that makes sense, i remember hearing about how they worked the engine in the C5 R now..

Have any performance spec's with the v8 in the catera? 0-60, etc...

The northstar Allante came out in 92.5 but was released as a 93. The Catera V has 500 hp and 500-lb-ft. 0-60-4.3-4.5
Holy cow 500 HP, thats awesome. What size Wheels are tires do you have on it I've been looking for some 5 stars to put on mine. Awesome, awesome car man!!

What kind of Rear end did you put in it?
I doubt the stocker would last 10 mins with a C5R.

Got a buddy with one in a Camaro, and he's busted 2 moser 12 bolts.

That is one nice engine,

I'm going old school, looking for one I can build up.

The rear end is a heavy duty unit from Holden, probably still marginal as it was used in a 350 hp LS1 powered car. The one in the GTO is not a bolt in because they use a different mounting scheme. I do not know if the guts will fit in a Catera Diff. The wheels are Steinmetz 17x8, tires are Conti Contac 235-45 -ZR17

It was in the car when I got it. It depends how you plan to use the car, if drag racing I would say no. For normal but spirited driving (the way I use my car) it will probably hold up because the tires are the fuse if you keep the shock loads down. John broke the stock rearend in my car with a couple power shifts. I would say the axles would be suspect under abusive use also. Still stock in my car.

while V8 and 6-speed is successful... which 6-speed tranny can be mounted to the original 3000cc V6? i only know Opel/Vauxhall's 5-speed can do the trick, but if there's a 6-speed i'll be much happier...

It was more complex than the current cts that lingenfelter is doing now which would make it very expensive. The previous owner did not disclose the cost.
