I have a question on driveshafts for a Maverick. Is there any difference in the sizes and which one is stronger. I have a 351w in a 1971 but it still has the 200 cid. driveshaft in it. I'm afraid it going to go "pop" with the 351. Unionmade
unless your putting out some serious HP i doubt you have a problem. i'm using the stock one. i've got a 9 inch with 4:33 gears and a spool. and have been running it at the strip for about 7 years with no problems. also this car had a 351w in it when i got it and i ran that motor for about 3 years.
