stroker life span?

If your not going to rev the engine you are throwing away power.

If the engine is built right and gear right, you might be surprised how well a high compression 340 motor can be. A 360 can be made with 10--10 1/2 compression also.

My 3.91 gear 340 car rarely goes WOT--there is no need to !

Ran out to a store this morning at 9am, temp was upper 30's, car sat all weekend in the garage. Fired it up and let it warm up 1 min, lots of water vapor, no blue smoke what so ever. 2 miles later I was on the expressway going 80 mph @ 4,250--4,500 rpm, engine was running great, only at the stop lights does it shake due to the cam.

Took the back roads on the way back--state boys on the other side of the expressway was doing a traffic stop and traffic was stop-back up for miles, ugh...I thought even if traffic thins out that trooper might still be around.

3.91 gears are perfect around town in 25 to 45 mph zones. 50--60% throttle in 1st or 2nd should pass 75% of the cars/trucks out on the roads, I had no problems staying ahead of traffic.

Drag racing is another story, I agree then stroker might be cool then but for my street ride no way. I beaten on my 340 for 2 summers now, got over 5,000 miles on it, red line is a "safe" 6,500. During the summer it sees 6,000 plus a few times each time it went out--some days muti times a day..sometimes in top gear--hard on the motor to push the car at high speeds. Uses just a quart of oil between oil changes each 3--4 months and the rear main has a little leak.

I never see any smoke expect water vapor from the exhaust. I'm sure that little 340 will last well over 50,000 miles.

I still don't see why not use a BBM if you want more CI ?
