Mike,

When I built the engine for 5165 (which now resides in the Jacksonville Sports Car Museum - https://www.jaxsportscarmuseum.com/gallery-1 <https://www.jaxsportscarmuseum.com/gallery-1>), I wanted it to rev as quickly as possible. Accordingly, I made sure the entire reciprocating assembly was as light at possible. I used a lightweight crank damper, lightened pistons and rods, gun-drilled crank throws, 157 tooth aluminum flywheel and a diaphragm pressure plate with an aluminum friction ring. The engine was internally balanced and had a solid roller cam, T&D shaft rockers, etc. It revved so fast it was difficult to keep off the rev limiter. I had none of the "buck and snort" you mentioned, when driving at low speed. I could easily drive at 2 mph in a parade or in stop and go traffic. Driving on and off a trailer was easy too. In fact, at parking lot speeds, it wasn't much different than when it was stock. This leads me to believe that the "buck and snort" you're describing is a tuning issue that is masked by a heavy flywheel.

My 2 cents!

Dan,

I was convinced to go for a Fidanza aluminum flywheel, and I think it's too light for the street.

Yes, it makes the engine rev faster which is entertaining. But it, coupled with a fairly aggressive cam, makes the car buck and snort when trying to inch along at very low speed. I have to use the clutch and rev the engine far more than one might expect-almost like a smaller-displacement Ferrari. Lori's engine has a stock flywheel and has pleasingly truck-like characteristics at walking pace.

An intermediate-weight flywheel would probably be the best bet.

164 tooth and personally I'd go with a billet steel flywheel for a street performance engine

Does anyone know what tooth count for the flywheel? And what is better for a performance street Pantera, steel or aluminum?

Thanks, Dan _______________________________________________
