Hi paulie
From what I was able to find out, this crank (C4AE 6303 G) came in the 64 427 HR and in the TBolts and is listed in the 427 7000 RPM Kits and was used as a Nascar Crank.
But I haven't found out anything about the 2 extra counter weights, I did talk to Adney after he received the crank and had a quick look and he said the counterweights could of been welded on after it was forged ? It's currently in the Crank Queue, so when it gets to my turn to get worked on maybe then he can tell if the counterweights were added or if it was forged that way ?
And as for the 391 crank maybe we can work out a deal, and I'll throw it in my 390, I am going to be putting a crank in it anyways, and I know I could have the one in it turned, but something tells me to replace it and the rods too.. I got screwed over on a set of FE rods I bought, they ended up having well over .040" side clearance, which is way too much, instead of eating their purchase price, since the outstanding seller isn't going to refund my money, I am going to fix them, I'll have one of the sides welded up on rods 1 thru 4 to take up the excess clearance between the pairs, and install them in my 390 after I work them over a bit.
Where are you at on your crank ?
Email me and we can discuss the FT crank
Hi Jay
It already has a windage tray, but I will keep the stock pan and run 6 quarts and restrict oil to the heads like you suggested on the 390, but I will get a 7 or 8 quart pan but it will go on the Side Oiler.
