Technical Notes: These engines are sealed at the intake manifold, cylinder head, front cover, and oil pan with special twist off bolt heads. The 350 HP @ 5000 RPM was derived from a superflow dyno using a 4 barrel 650 cfm Holley carburetor P/N 80541-1, 32" long by 1 5/8" to a 1 3/4" stepped header with a 3" collector, and 92 octane unleaded gasoline. This engine package DOES NOT include a water pump. Oil pan clears most GM rear steer chassis with stock engine location. Oil pan is 8" deep at sump.

They have been runnin these types of engines in late models in and around the Carolina Speedway area for a couple of years. When i used to run in that part NC they were just getting started and when the tracks dried out became very quick. If I remember right the max. rpm on these engines was something like 6800. Since then I've heard that Clements has figured out a way to "work" these engines without being detected. This was a very competitive class based on driver an car setup, I think it should be a class considered by tracks in this area

Sorry to tell yall there are alot of slm fans like me that wont pay 50cent to watch a crate race. Nothing against the drivers who race them(some big names now) But when you dont the hammer if the it doesnt make the hair on my arms stand up or the sound doesnt ring my ears you can keep em. Get the point my self I hate watching a crate late model/ A late model is made to run 800 horseposer wide open

If it came down to a Crate Race near home or SLM race 3 hours away I guess I would be traveling. Down at Golden Isles Speedway this past Febuary, that crate race was probably the only one I've seen worth talking about, but still the SLM's made that trip worth wild.

I wasnt sayin that i prefered them cause SLM is where I'm returning to. I was just sayin that instead of these LLM classes that tracks a saying are to give young drivers experience that would be an option.

Everyone likes horsepower but it is just getting too expensive. Soon even the steel blocks are gonna price themselves out of existence. I've raced street stocks for years and worked on SLM's before that. Just getting into the crate stuff. It's the only way I can afford to run a late model. You may not want to pay to watch them but I'm sure they are fun to drive. Face it the days of tracks all over running SLM's is over. As costs continue to climb there will be more and more tracks that have to abandon them. In a perfect world we would all own an all aluminum 430. Let me know when you find that perfect world.
