754 cam in a 302

[Lynn]

I put a 140 cam in a 68 Z back in 1970. 4.10 screw and it ran awesome. That guy regularly shifted at 8k. I do not know if he had an M20 or M21.

My Z has 4.10 gears and an M20, so when accelerating, you aren't below 3000 rpm for long at all.

I ran the 140 camshaft in my car back in the 90s, and it was a LOT of fun, but not really a cruiser. Great power once you get to the 3k mark. Shifted at 7k, but it sure FELT like it would keep pulling forever.

Surprised you have had an issue fouling plugs. I never did. I used an HEI distributor back then (points work fine on the stock cam or an LT-1 cam) and remember using a different PV.

But then, the stock 302 isn't that great of a cruiser either. My 4.10 gear with stock tires means I am humming along at 3600 rpm at 70 mph.

I don't see the point in going with the 754 cam, other than the nostalgia. But, I GET IT for nostalgia purposes. If you go that way, and you have an M21 or M22, you might want to consider something even steeper than a 4.10 screw. I have a really nice set of GM 4.88 gears. Not sure why I bought them. Was thinking of doing a FAST car or even Pure Stock class. Have given up on ever being able to track it. Besides, now all the tracks around here are closed.

Just my two cents.
