new crank!!

My New Bryant Billet 5.300 stroke crank showed up today for my 712 !!!

Frank

Yep its puuuuuuurrrrddy

couldn't sleep !! had to go back to the shop and measure the crank and hang a rod and piston on it to see if my math was right !!! and it fits!!!!!!!!!!!!!!!!

Frank

with a 5.300 stroke and a 4.625 bore and a 7.190 rod with a 1.350 compression height flat top piston with unmolested valve reliefs makes 14.5 -1 and I'd like to be 13.5 - 13.8 to 1 (some massaging on the Valve reliefs will get us there) for all the nitrous were going to throw( 4 -300hp kits) at this motor . it's sure as hell will make the car run !!!!! HARD in the top end!!!! 2250 hp will do that!!!

Frank........you a wild man

I can understand why you couldn't sleep !!! Thats a pretty Piece !!

Whats it weigh in at and How did it balance?

You should charge people to look at the picture...and charge more...if they want to touch your crank.
That is very nice!

Nice crank Frank!! I'm just glad your good at math Your son had better be ready for the ride of his life!!There must be a really fast street car lurking around somewhere for you to build something like that

Thats going to be one hell of a "Well Pump" Motor !!!

NICE !!!!

Just like a kid with a Christmas present, they have to play with it all night long. I think you are going to give them guys with the Leonard engines a handful when you light that thing up.

that's my intention Schmitty , this Bad boy should run Hard!!!! Kaase said it my be a tad hard on valve springs with the 1.060 lift cam thou!!
Frank

thanks Frank! now i know why it's took so long to get my little 4.5 stroke! i'd sleep good if i had that crank,it'd be in bed with me!
