Where do you find the cylinder center-to-center measurements for engines? What head is "the alloy head conversion Jack has done?" Thanks. Mark.

Ooops. I thought I was relying to "Another head question" thread. Sorry.
It's okay!
All the small Fords, 2.3/2.5 ohv fours, 144/170/188/200/221/250 and later OHC 3.2,3.9 and 4.0 liter I6's run 4.08" centre to centre bores.
The data gets stollen from friendly, astute forum members who are thinking about the same thing you are...head swaps!
I got Heathdaily to check his XK6 engine, and it was 3.8125" centre to centre at the head studs.
The L-series Nissan 240C/Z, 260C/Z, 280C/Z, 280 ZX and related Z20, Z24 and L16/L18/L20's engines in early Datsuns were the same at 3.8125" centre to centre. (My measurements)
The Slant six runs a variable bore spacing, with 4.00 inches except at the outer ctylinders, which are 3.98" or so. Care of the Slant 6 forum, and just one on the fine blokes there who was a real gentlemen.
The Chevy L6 is about 4.4", same as the Toyota 2f and 3F engines found in the Landcruisers to 1988.
The 240/300 is about 4.48".
The 232/4000 Jeep six is reputed to be a lot wider in the bore spacings, but I've not had it confirmed.
The early Y and I block Ford V8's and I6's were supposed to be 4.4" bore spacings, as they were related. The crank from a Y-block 312 can fit into a 350 block, which is 4.4".
I've heard tell that the AMC v8 is about 4.75".
The FE engine is about 4.625"
The Cleveland, Windsor and 400 is 4.375".
The Cologne V6 is about 4.78"
The Essex 60 degree is 4.32" (SHO, US Vulcan 3.0, British 2.5/3.0 V6)
The Essex 90 degree (USmade, 3.8/4.2 lightweight engine) is 4.375", but has a bank to bank offset of 4.375/2 + the crank flange distance between the con-rods.
The Lima OHC 2300 has a wider bore than the related Pinto 2000. The Lima is 4.17", the Pinto is 4.017"
The Modular Romeo/Duratech/Triton 4.6/5.0/5.4/6.8 series is 3.937".
The Lima 385 and the realted MEL 430 engine is 4.9"
I can't remember what thee Chevy big block is. About 4.75", the Mopar is about 4.8".
The 313/318/273/340/360 is a 4.62" bore spacing engine.
The Colombo and Lamperdi Ferraris are documented, as are the BMW and Mercedes engine families, along with Porsche 901 and 928 based engines. If you want to do a search.
This hard data requires quite a bit of digging to get, but if you are persistant, you can find it!
