how much to bore my engine

[Pirate]

Hm.... maybe I was remembering wrong, then, maybe it was more like 420ci or so. Does look like you'd need a 4.28" bore to make 460ci with a 4" stroke. Do you happen to know how far over fancy aftermarket blocks can go?

4.185" capability (.060 over) with the current round of aftermarket 4.125"-bore 351W blocks out there...but there isn't any need to go that far, short of bragging rights. However, if one wants a 460 Ford in something other than 385 trim, I believe I have a link to one based on the Cleveland in my race forum...

454 cu. in.
FRPP Block
4.125" Bore
4.25" Stroke


You can get 4.17 and 4.25 stroke cranks for a Cleveland too. Probe makes a 4.25" Cleveland crank for example...... That has to be major block sleeve work to get any "Cleveland" 1/8" over....

the new boiss 302 can be bored .125 over, when are they gonna make a new boss 351...?

Welcome to the 80s...
They already make a 351 block..... You can get it in a Cleveland or a Windsor deck height.....
The original Boss 351 block was a pile of shit........ Thin walls, piss poor oiling.....etc.. No reason to make another one like that.
The Boss 302 on the other hand was intended for actual racing.....
