Dont expect much if any aftermarket stuff.

I dont really have to worry about the aftermarket support Lingenfelters shop is only two hours away and the tuning shop they use is about the same distance. After i get a gasket refresh done on the motor and new oil pump the only thing i plan on doing is stroking and tuning. Thats all the same basic stuff as any SBC

Remember, that motor is nothing like a regular SBC, it was designed and built by MerCruiser for GM. The bore and stroke were both different at 3.9 by 3.66 in (99 by 93 mm) instead of the usual 4 by 3.48 in (102 by 88 mm)

yep, ya beat me to the punch.

http://www.zr1netregistry.com/ZR1_about.htm

LT5 engine, an aluminum-block V-8 with the same bore as the standard (L98) 350ci displacement unit, but with 375 horsepower. To accomplish this power boost, the new block featured four overhead camshafts and 32 valves. The LT5s were built by Mercury Marine in Oklahoma and assembled into the ZR-1 vehicle at Bowling Green.

Klortho

They actually didn't have the same bore size, but they had the same bore spacing. The motor is all together different than a regular SBC.

subscribing. I really wanna see lots of progress pics and stuff for when this swap actually happens. It's been done before, but actual progress pics will definitely be neat

Just drop it in as is. How many miles are actually one it? What happen to the car it came out of?

Pic's of LT5. what year engine is it?Any pictures of the car its going in?

mackjar66

iTrader: (9)

it has 46343 miles and the car was rear ended by a dump truck

Klortho

So if it has been tweaked by Lingenfelter...what has been done to it?

mackjar66

iTrader: (9)

nothing has been done to the motor yet. I am waiting to get back from Iraq before I decide on anything. Lingenfelter quoted 8 grand for tweaking and the tuning guys quoted 500. But it also depends on which motor I have. They told me they didnt serial their builds until 2002 so Im waiting on the cars VIN so they can tell me what exactly has been done to the motor already.

Klortho

This would look sweet under the hood of my GTA

I agree, id trade my 383 lt1 for a stock lt5 for under the hood of my vert..lol

put my novi 2000 on the lt5 would be fun.

There was a fellow over on tech a couple months ago put a LT5 in a 84 vette and a couple turbos. He had $3200 alone in 4 custom cams

LT5. My dream engine. Gaaaaaaaahhhhh....*drools*

novaderrik

did this ever get built?
i got to drive my uncle's Haibeck tuned 92 ZR1 last fall- even with a dyno chart that shows 450HP at the wheels, it didn't impress me all that much..

abray1

You are hard to impress. I have a 90 that makes 430 to the rear and winds forever and it is one of the greatest engines ever designed. That much power with a smooth idle and perfect street manners. Cams with only 390 lift and flow over 300CFM.
