| some are, but I know of a few 350's on VP race gas that would run those times. A friend of mine has a 350 for sale that ran a 4.3 on race gas first time out of the shop, no tuning at all.

| Andy from GRR built some really fast "350" motors! A buddy of mine had a couple of his experimental motors. They ran 11 sec. 1/4 runs easily.

| usually it takes alky to run mid 4's on a 350 in 300 feet the track has *alot * to do with the killer times you hear about for 200 feet id say 3.2 seconds would be pretty fast for a 350

| id say you could have a very quick bike if you could get the rear end set up just right where it hooks up good and get a wheelie bar setup good to where you can launch the thing super hard and get a good jump off the line without it making the front end bounce hard. do you think a lockout clutch would be needed for a heavily ported 350? or could you get away with a good billet clutch basket and barnet clutch kit and hd springs?
