this is a great thread , i'm currently going to build a 572 wedge , 4.5 crank n 4.5 bore . i've got pro ported stage 6 chapman mopar heads and mopar max wedge intake matched and flowed . is this a good combo ? going to put in my 63 sf vintage drag/street car . i have a couple external oiling pickup systems . but i read here a internal pickup can work as well . what else shouild i be looking for on my build . my machinist will do the work i tell him to do , so what is needed ? using this block and crank .

Not sure what block you have there but I think you’ll be looking at like a 4.350 to maybe a 4.380 bore

did the sonic test on it . its 4.380 now and has .212 on the thickest , .180 on the thinest of the thrust side of the block . these were the last of the ind 440's made . so my new bore takes another .06 per side . and my machinist said he could fudge that abit .

Probably Bryant Racing, never heard of a factory production block going 4.5, might be a one of a kind
 
my cam grinder said that that the end of the rb blocks being built for big giant equipment like ind use or city buses , brandly tank . and hdgvw these were cast in 78 .

It’s definitely a Bryant crank. Most of those don’t have a flywheel locating register or converter hub on the rear. The largest bore I’ve seen on a factory block was 4.400 but it wasn’t a high hp engine or a stroker.
 
bryant crank , it doesn't have a flywheel reg collar on it . but the crank guy , my cam grinder knows is going to set it up for me . well that block might clean up at 4.4 , but i just figger on 4.5 is it for this blocks bores . and being the bores have .212 thichest n .180 thinnest on the thrust side of the cylinders . with a 4.38 bore now .

Won`t that be getting pretty thin on the thin ones ? Might be better off to sleeve those .??????
 
well i'm still in the ordering game on the pistons , and the machinist hasn't done a clean up bore yet . and yes it puts the thinnest thrust side down to .120 on the cylinder . and the fattest at .152 on the cylinder . keeping it cool might be an issue on gas , could step up to e85 .

That would worry me, what kind of compression u going to run? Be a ***** to blow a hole in the cyl. wall !!
 
its to run on pump type fuel gas @10 cr or e85 @11 cr . going to turn it @6500 . thinking the lumbering monster can run 9's .
 
It’s your motor, but I would try to go to 4.40 as Hemirunner mentioned. Good luck with it.
 
well i'm shooting for the smallest bore that we can clean it up at being its 4.38 now . and of course i wish keep the piston costs down . who's pistons should i be looking at @ 4.4 bore ?
 
Diamond, JE, Ross .... btw those cranks usually have cracks that can be removed by grinding down to 2.20 rod journal. But often are cracked to deep to remove

sending it to my cam grinders crank guy . he's going to check it and fix any issues and add a hub reg for the flywheel and or torque converter . and i'm looking at all these brands now , ross didn't show any less then 4.5 bore . but again this block still needs a clean up bore . then i'll be real on what size bore it can be .
 
4.40 and 4.44 are common big block ford sizes. You can have pistons made for your motor in these sizes and have rings readily available. Take the crank to 2.2 and get a 7.1 Molnar rod in mopar width - DH7100VTB8-A
 
yes , thanks i just found them at diamond in those bores and 4.5 stroke . and the 7.1 .990 2.2 molnar rods are the plan . do you think ross or je or diamond wiseco , whats the ranking between the four ? i think three of the four are under one co management now . my plan is to use the mopar stage 6 alum alloy heads their pro ported by dave story of story porting in crestwood , ky . my cam grinder used him for the wedge stuff . he built a 468 b wedge 850cfm 8800rpm 803 ponies all iron motor with my buds cams .
 
Actually you might want to see if it will clean up at 4.39, also a common ford size
 
i'll be bring it up to wade at hubbard machine in hayward ca soon . he has two more of my rb's in build , close to being picking up . and wade and jimmy are great guys that know there stuff .
