Well maybe the Brazilian L6 blocks have more meat, because some builders fit 4.03" pistons with stroker cranks and the engine live almost forever at 15:1 CR...I don't like that because the cooling problems..ProPower engines wrote:No a 194 head is from a 194cid block.
It was the first engine of that model run then came a 230 then a 250 ect.
We put 1.94 valves in the head but needed to massage the chamber quite a bit.
The 230 head work out better and with .080 off was about the same size in the end.
Going to 4.00" is getting real thin and especially #1 hole behind the water pump.
if the sonic checked the block I would bet they may had .080 of cyl. wall left and # 1 would be paper thin. What ever floats your boat I guess but would not go out that far with out sleeves in at least #1 and #6. Seen too many crack.
