5 MILL WITH GAS

[BUSA750]

HOW OFTEN DO U HAVE TO FRESHEN A 5 MILL WITH NOS 100,150 SHOT BUSA WITH A 1397 UP TOP.
TRACK ONLY

stock lenght rods? short rods? bearing clearances? oil mods? how often you miss the tune up? all that stuff will play a roll.

nobody can say for sure. i dont do it after a set number of passes, i change the oil after every day at the track, and check the filter. if i see something i dont like, i send the oil out and have it tested, and then based on those results i decide whether to take it apart or not.

I HAVE A 2 MILL 08 CRANK IN IT 1441 AFTER 50 PASS BEARING LOOK GREAT JUST WANTED TO KNOW IF A 5 MILL WILL GET SAME RESULT.


I KNOW THINGS HAPPEN

there's really no telling for sure. it could take a shit after 5 hits, or last all year and be fine.

 I personally would stick with the two with gas , just add a little more juice to it. The biggest benifit w/5 mil would be more torque before the hit..
If you do it use standard length rods w/spacer......m/o.

 & clean your oil pickup screen often + depending on your 60's use windage tray &/or 1" pan w/swivel pickup.
