Re: is it possible??
no, you cannot bore that block out, it is basically at its maximum safest bore already
and for an overbore, you only really need new pistons, rings, and a bigger head gasket (although most of the time they are already oversized)

the 3.8L is an entirely different block
it is probably possible to stroke it to 3.8l, but it would require a ton of block work, there is NO WAY the cylinders could be bored ~.20 over... SBC blocks have a hard time with .060 over, in order for an overbore, that 3.4 block would need to be bored over 3 times that, not to be mentioned would also need a (probably) custom crank
doing so would greatly affect the integerty of the block.. not to mention the cylinder walls would overlap

so purchase a 3.8 block, you can get them a dime a dozen..

Re: is it possible??
he coiuld try overboring & sleeve it, but it might be cheaper to get the goodwrench aluminum block (if it's even still made).
While I haven't perused the forced fed forums, take a look at what they've done for more power, and even look at what Tiago's set up was (the infamous forced fab iirc)1978 Formula 461 in progress of being built :rock:

Building the Tom Henry RS
Part 4: Suspension Mods, Tires, Wheels, Headers and other Cool Stuff.
By: Hib Halverson
At the end of Part Three, we changed the valvetrain of the 3.8-liter V6 in the Tom Henry RS. We installed new, Yella Terra "Ultralite" 1.8:1, aluminum roller rocker arms, Katech valve springs and Katech titanium retainers on our 3800 Series II V6.
Ultralites are nearly 25% lighter than the stock 1.6 rockers and 8% lighter than the SLP aluminum...02-07-2020, 10:30 PM
