Does anyone know what the bore spacing of a 215 Buick block is?

Same as Buick 300, 340, 350, Oldsmobile 215, Repco, Rover, and early Buick V6.
Compare from my table here: http://victorylibrary.com/mopar/m-table-c.htm#B6

It's not all good, they're taller and wider than a 5.0 Windsor.

I remember them best from an MG I had many years ago. Seemed cool to have the only english built car with an american V8 that came stock production.

Hello:

Not sure if you are also this guy but I noticed the Gen III Chrysler Hemi bore center is listed at 4.09"

http://victorylibrary.com/mopar/bore-center-c.htm

I believe it should be 4.460" ??

Great site!!

Thanks
Randy

Fwiw, if not mistaken, David Ray, (aka, Ignitionman), can tell you how to bore and stroke a 215" BOP aluminum V-8 out to 300"s or so.

Drop it into an early Vega and have a, "stop light to stop light", giant killer car!!

He, He!!

Heck, install it in a Chevette and one would be a hoot, imho!

Have you sleeved the 215 block for bigger bores?

We used to race then on boats years ago. The limit was 230" so the good motors were re-sleeved and bored .100 over

MG, Triumph, Morgan all used the Buick-based V-8.

Jensen used Mopar big blocks--383, 440, 440+6.

Of course, there were the Sunbeam Tigers with SBF power, but those were engine-ed by Jensen, the way Shelby did the Cobras.

> Have you sleeved the 215 block for bigger bores?

I have a Rover 3.5L that was sleeved to the larger Rover bore (3.7" as used in 3.9L, 4.0L, 4.2L and 4.6L Rovers). It has a 3.5" stroke crank with 6" rods and custom pistons (Diamond forgings) and has been cross-bolted. It's much easier to start with a 4.0L or 4.6L cross-bolted Rover block. With a 3.4" stroke Buick 300 crank, displacement is around 294 cubic inches (assumes 3.71" bore). The Rover 4.6L crank can also be offset ground to get to around 4.9L. Some have discussed offset grinding for small Honda journals but I've not actually seen one in practice. I know one guy who fit a 3.85" stroke Buick crank. He re-routed the oil pickup passage to the outside of the block and ground rod bolt clearances into the old passage. The old (circa 1985) Phil Baker article used 3.75" x 3/32" sleeves for some of the larger displacements. From the "Affordable Aluminum V8's" article:

"Baker uses Ohio 231 sleeves, SL 4150 or SL 1121, the former ones being cut in half and used to produce two sleeves for the price of one"
