building my first 306 and have a few questions..

I have read the 400 Horsepower 302 Buildup article on this site and it is informative to a point. Anyways, I will just start off with my questions.

1. Why do the builders put the bead of silicone sealer on the block and is it necessary?

2. Is it necessary to put moly on the crank bearings or will plain oil work, also is it ok to oil the whole bearing, crank and block side?

3. Do all of the ARP main stud kits offer the one bolt with the threading ontop to attach the stock oil pickup tube?

4. Now a cam question... F303 or Ford 5.0 Xtreme Energy EFI XE270HR Cam http://www.powerandperformancenews.c...ry_Code=35-CAM

or is that too much lift with 1.6 rockers??

Thanks in advance...this is a great learning project...and I now have two 89 gts...one stock daily driver...and the other with the engine pulled, machined, and balanced.


Also if you would like to email me with any tips it would be helpful. winterbomber@hotmail.com Thanks!

#1: because the stock cork gaskets don't seal worth a flip compared to that bead of silicon

#2: you might get away with it, but better safe than tearing down a motor again or replacing parts. Go with what works.

#3&4: i'll let the guys that know more than I do answer those

If given only those two cam choices go with the f303. The XE270 is pretty much a stock cam with more lift. A better choice would be to call cam research and get a custom cam. ( right Tony ? )

yeah I am seeing your point about the cam..now... so confusing sometimes. thanks!

#2. The back side of the bearing should go into the block dry and [b]clean[/i].

#3. No.
