[h0trod389]

wassap folks!

i just picked up a 63 389 with head # 543797's for my 1930 olds.

i had a few questions about this build.

my plans are using the 4.25" eagle crank. when i bought this crank i also purchased the 6.800 BBC H-beams.

everyone is tellin me to run later style heads, but i want to utilize a old hilborn injection unit for early pontiac.

i know that these heads are closed chamber and i prolly wont beable to use these 6.8's with these heads.

should i run a standard length rod for this application?

or should i build a 400 instead with a set of 6x-4's, and a adapter plate for the hilborn?

last question, the bell housing bolts are 7/16" instead of the regular 3/8" bolts, was this common? or did someone drill and retap?


last time at the track i ran a junkyard 400, lost compression in #5 and still laid down a 13.3 @ 104

i want to reach atleast high 10's!

P.S. THE SHEET METAL HAS BEEN REPAIRD ALREADY..hahaha
