Happy New Year everybody!
It's been awhile since I've posted. I haven't had much to talk about.
My 1965 GTO 389 engine is in the machine shop getting rebuilt slowly, but surely, which suits me just fine since I don't want to swap out engines until spring anyway.
My topic is clutches. I am starting to accumulate pieces that will be used on my rebuilt numbers-matching engine, such as H.O. exhaust manifolds, and one of the other items I will change on my car with the engine changeover will be the clutch.
Now my engine is getting a relatively stock/street makeover. I had to take some extra measures to get that notion into the machinist's head. He pushed for a 4 for 7 firing order swap/Howard's roller cam and I really don't need that in a restored '65 GTO convertible. I talked him into using the Summit 2801 cam (also sold through Jegs, Crower, Sealed Power, Speed Pro, among others) which is like a 068 cam with more lift. Now we're on the same page and he has been working on my engine over the winter months.
So my engine will be relatively stock with a few upgrades. It will be a 5,000 to 5,500 RPM redline engine that will rarely even see 5,000 RPM. I am using the original 3.23 axle, and the car won't ever be on a race track.
I have used a stock replacement clutch for the 12-plus years I've had the car restored with the correct, non-numbers matching stock WT-code 389 without any issues.
My question is should I stick with a stock replacement clutch, or upgrade to something a little tougher? I checked out a Ram clutch (#88760) that is touted as a compromise between a stock clutch and a performance clutch. AMS has a similar one sold on Rock Auto.
I know I don't need a racing clutch, but I wonder if I should get a clutch that is a little stouter than a stock replacement.
As always, I appreciate and value your input.
