Hello I bracket race a 58 Olds with a 371 and have just found a 394 and a B&M for maybe next yr or the yr after $$$$$. I am missing the 394 valve covers,oil flt adaptor, and maybe more when i go threw it all. I would like to know the formula for bore and stroke a 394 to 482,do i chew the light aftermarket pistons by my teeth or can you buy these done already? What light rod?,does eagle make a rod like a 425 or 400 7 inch rod for a 394? My B&M came with a chev ft. housing and small dia fluid coupling. The olds frt house is on there now and a slant pan Olds fluid coupling. The seller told me the vanes from both looked exactly the same when he swapped them. I heard there is a bigger stall speed with the larger Olds coupling anyway? But as per the B&M info i have read the Chev. coupling must be used? Niether were brazed. But this is suppose to be a intro so... My 1/4 mile times with a 58 88 371 4 speed hydro. @4240 pds. 15.288@90mph. Offy 3x2 intake,homemade in chassis headers,mild trw hi pro. cam(only one i could find),31 spline 64 caddy 342:1 posi pumpkin in the 58 housing(axles cut),MSD. I am gonna need some help this coming winter with. Thanks for you all being here. Good luck and drive safe Randy H.

Thats really cool to see a Olds still tearing up the quarter mile. Welcome to the HAMB. You might want to ask your questions on the main forum so more people will see it. Good luck.
