Lt 1 ??

On average how many runs can you get out of a LT 1 Stocker motor before you should freshen it up. That?s if you don't hurt any thing.

dean ribeiro · 08-10-2007, 11:30 PM

depends on how fast you are looking to go? typically if you are not concerned with slowing up a little, 110-130 runs is a reasonable expectation before you should freshen things. I would keep a regular check on valve lash, oil condition etc..

The 98 Firebird I drove in D/FIA (@ 3875 lbs) for the Emmons the last 3 years had 306 laps on it when Jim freshened it earlier this year and would still go a second under in good air. Constant preventive maintenance and frequent changes of the Lucas oil and a fresh K & N filter certainly helped.
Jim Hanigs report on the engine after he went through it was that one rod bearing showed a very minor nick right at the edge. Other than that it was still looking good inside.

My LT-1 engine has basically the same ring package many bracket engines would have. It has a roller cam so there is no worries about lifter or cam wear. Other than possibly installing some new valve springs and checking over the rockers and pivots there is no reason an engine can't run as many laps as Bob and Jim say. I have built bracket engines that went 300- 400 runs and still looked fine inside and they had flat tappet cams, more compression and saw the same rpm levels.

Rich, there is a K & N air filter that will bolt right on your Throttle Body, it is for a Marine application, Run's the same ET on or off, a very good piece.

bob shirley · 08-17-2007, 11:00 AM

wj,
do you have the partnumber?

Woodro Josey · 08-17-2007, 12:11 PM

Yes Sir,,,,,,,59-5020 K & N Kinda hard to find in a parts store!

Rich Biebel · 08-17-2007, 12:19 PM

Woodro...I got one like we talked about but it hits the t-stat housing. It is somewhat oblong shaped and the flange goes directly on the t-body, perfect fit. It will not go on with the t-stat housing in place as the lower part of the filter hits that housing. The one I got is KN part # 59-5050. It's listed as a marine spark arrestor. If there is one that fits with the t-stat housing in place it's not the one I have.
