does anyone know what the valve clearance is on a stock 1990 v6 3.9. i know the stock length of the pushrods are 6.740 and what i was wondering how much clearance was there b/c i want to go with a longer pushrod instead of going with roller rock change much cheaper this way. the pushrods from a 92 v6 3.9 are 6.900 in length. any info will help. also the cam from a 92 has a bigger lift than the 90 would there be a clearance issue if i leave the stock pushrods and go with this cam or even better with the longer pushrods and this cam..again any info will help

Check that site and see if it tell you what you need to know. I know it has that info for the 5.2, which near identical to the is a 3.9 but with 2 more cylinders.
