well you can build the v 454 out to 489/496 were you could not go with the 396 but the v block is not the same as a IV block so some things can work some things can not. older heads do not fit up very well on the open deck. i do not used them other say they can if????. i do not use older heads on the V VI blocks i checked it. two pc seal crank can work with adapter oil pans are not the same .stock V and VI need some work. valve train. the VI is a better way to go as it comes with HYD Roller cam set up. i have a VI block and others core blocks that can be built as a short block to long blocked

yep still half a sleep about late 90 to 91 was the first year for the V block and mid 90s ? then GM went to VI all about the same but for the hyd roller hold downs casted in the block for roller cam set up and the cast front timming gear cover

So it sounds like $500 for a Gen VI is a good path, assuming you know it to be a good engine, just for the hydraulic roller lifter feature. Are you still looking at having it punched out & building it up?

well my engine build keeps changing due to new info...i decided not to go with 454 gen6..reasons being i just found out from the machine shop that my 402 (4.125")is actually bored out to a 454(4.250").. have money and time already in it..so imma just stick with it until a second build. I knw sum r sayn why but..ive grown fond of my current build..Next question would b what r the best pistons,rings,rods and main bearings 2 use? A recap of build is a 402 with 454 crank and heads, with a 4.250 bore..its a converted 454 rite?

sorry i can not help you .I am done

Very strongly suggest that you beep the cylinder walls before proceeding.

As Tech said, think I'd do the sonic test first, that's a big cut on a cylinder wall! What parts to use depends on what you're going to do with it, I suppose. All out racing, cruizer, or a Saturday Night Special? We freshened the old 501 drag engine with Mahle pistons, King bearings, Childs & Alberts rings (plus the Zero Gap 2nd ring), that was about 200 passes ago and it's still running strong! Seems from my somewhat limited engine building, the 2618 forged pistons are well worth the extra money if for no other reason they seem to have better quality control in the manufacturing and machining processes, same thing with the King Bearings, C & A rings. Just my 2 cents worth on what seems to fit good and last a long time for me. More important IMO is the fit of all the components and a very first rate balance on the internals prior to assembly!!!!!!
