$3,000 for the block

Then you got to bore it. Just say you want a 4.100 bore. That is .190" worth of boring. EXPENSIVE.

I would not spend that kind of money and still have 59 degree lifters with 1 7/8 lifter spacing unless I was dictated so by class rules. Just My Opinion.

if at all possible go 48*.... I was lucky
when I bought my 48* siamese 9.20 block... it was
new but I got it at the Indy swap meet... I still
had to bore it, cam tunnel 50mm, mains and the cyl
bores.... which they all need... but I only payed
$800 for it
