I just like them to pull out even better. My friends ran a 1957 chevy 2 door wagon in G/MP back in the 70's-80's with a 288 inch motor a 6.17 ring and pinion , a Nash 5 speed with a 3.00 first gear and a 50 lb. flywheel. Needless to say the car was out of 1st. gear by the time the rear bumper passed the tree. They were the national record holder in 1976 at 11.33 and went as fast as a 10.82 in 1979-1980 right before they scratched Modified Eliminator from NHRA. I think the car weighed 3,500 lbs also. I learned back then it was about the gearing. </div></div>

Gears rule, now a days it's all pro touring and overdrives....I say if you wanna go down the highway at 1200 rpm buy a Honda. As little as I drive mine, nothing compares to the sound of my SBC sreaming down a country road.

I ran a 140 cam an never found it to be unstreetable. I ran mine straght up but recurved the distributor, and ran the vac advance to manifold vac. I know some guys swear by this cam 4 to 6 degrees advanced. I really didn't think the idle was that much lumpier than the 30/30. Instead of 900, I set it about 1000. No big deal to me.

I never had plug fouling problems with the 140.

4.10 gears and wide ratio muncie.

If I still had a 140 cam, I would not hesitate for a second to put use it in either a 302 or a 350 with 11:1 compression.

In fact, Bill, if you want to trade your used 140 for a used 30 30, I can do that, and would pay shipping for both.
