Small Block Tractor Test Run
This is a short hastily throw together video of me trying out my sister's
pulling tractor. There is something I should make clear before it is asked:
1) Yes I am wearing Crocs.
2) It was laundry day, I don't normally ride around in over sized sweat
pants, tee shirt, and some Crocs.
3) I don't care what you think about Crocs.

350 with Comp Cams Magnum 270H 112 LSA and 4/7 swap
This was my first time swaping a sbc cam. I left the 081 heads stock on my
350, but put new extreme push rods, 270h cam, and lifters. So, you can run
a .470 lift cam on stock heads. I spent many weeks looking for that answer
ans now I have the experience for my self. I also could not find a good
sound clip of this special grind cam online- so now there is one....enjoy!
Comp Cams Magnum hydraulic flat tappet grind #12-211-2, with two changes...
it has the 4/7 swap and LSA is 112 (instead of 110).
Built for 1.6 rockers, lift is .501"/.501
(If used with 1.5 rockers, lift would be .470)
Chevy Vortec lifter & valve tap how to repair it
this video has info on how to fix a severe valve tap or sticky lifter using
1 quart of automatic transmission fluid with 4 quarts of oil. the trans
fluid is a high detergent that loosens up sludge build up in a motor from
lack of oil changes, you will be amazed at what pouring 1 quart of trans
fluid in a neglected motor can do. the truck in this video got a double
treatment and now runs smooth with no taps and the check engine light went
out as soon as I started it. also after the second treatment I changed the
oil & filter and the clumps of sludge that were left in it broke down into
the oil from the trans fluid and it flushed it out. I
I realize I bash fram oil filters in this video and any filter wouldnt have
helped in this case because the truck was so neglected any filter would
have pluged up. howerver,,, Fram in my opinion is cheap crap.and over the
years of having hundreads of cars I can honestly say if you have 2
identical engines 1 using Fram the other using Wix or Napa the Fram motor
will die prematurely due to lack of filtering.
