Does anyone have the 320 bore spacing dimensions at hand? I live in a metric world, and I'm lost with the fractions
 
Jyrki,
I don't have the dimensions but if you have the dimensions as fractions post them and I will convert them for you.

i'm not sure how i dug these up ( i also have the pitches for the Duesenburg Model A but not the J ), but this is what i have for the 320:


Piston
# spacing "
1
4.075
2
4.290
3
4.075
4
4.545
5
4.075
6
4.290
7
4.075
8


of course, 1" == 25.4 mm so
4.075" == 103.505mm
4.290" == 108.966mm
4.545" == 115.443mm
 
Jyrki, If you noticed, when Buick originally built the srtaight 8 it was designed so that they could use much of their 4 cyl. tooling. If you split that center space in the middle it is the size of two siamezed 4 cyl. heads. If somebody made some aluminum heads for the 350 Buick I think that you could massage them to work. The 64 300 heads could possibly work, too but may need some valve repositioning to get a little larger valve. Otherwize it's back to building a scratch head. Doug

ah, TA has already had Rover / 215 / 300 / 340 aluminums for sale? i don't see them in the catalog so i don't know if they only made a limited run, or what.

you know, i never thought about that. the SBB with 4.240" spacing is only 0.28" longer from cyl #1 to #4.


while we're on this subject, does anybody have the bore pitches for the 248 / 263? it seems silly that i don't have those.

it was?

and you know the pitches for these?

dude, pitch em too me. i'll build a wiki page for the earlier Straight 6's, 4's and 2's from early in Buick's history.
 
Thanks, Bob, that might be worth looking into. Wonder if anybody makes an aluminum Poly head? Edelbrock? Doug
