10w-40 would be my choice.

It's not a midlife crisis, it's my second adolescence.

wow really guys...I've always used straight 30 weight, and ive got my engine in to a rebuild shop right now and thats what the guy reccomends on any older engines.  Course I live in Oklahoma where summer temps get up past 100.

after approx 5000 miles you can switch to 5-50 synthetic,  just don`t do ti before that to let the rings seat in properly

My 383 will be close after this sumer. Will 5W-50 synthetic make that much of a difference? I mean power or engine life.
If it ain't wide open; it ain't running.        Rule number one in motocross racing: Pin it; row the gear box; and wait until you hit something.     At work my motto is: If you need me, call someone else.

Yes , it has far better resistance to heat & breaking down of the oil  it also will free up a little HP , I use synthetic in the diff & tranny too

I will keep that in mind. I may only have 3000 miles on the motor but I have around 30 passes at the track. I will think about it at my spring oil change.

I've been using 10w-30 in my car but I may try switching to synthetic this year myself.  It's expensive but I waste money on much less needed items for the car so I might as well do something useful.

possibly but not nessisarily , it doesn`t hurt to retighten a lot of the places fro potential leaks like oil pan , valve covers, intakes etc anyway

Why would it develop leaks switching to it later on?

there are a few reasons why this can happen , if the synthetic cleans better it can remove carbon deposits & if the seal is hardened it may not seal as well on the cleaner surface

It's fair to say then, that a higher mileage engine could develop these leaks even if it had the synthetic from day one?
