Was in the local machine shop yesterday, talking to one of the guys about my Rampage project, when he told me about an interesting project they recently worked on for a customer.
Gary(the M/C shop guy) said they had a customer who had them cut a Chevy V8 (I assumed Small Block, but didn't ask specifically) in half, "the hard way", to make a V4. Gary said the guy was using a pair of Subaru overhead cam heads on the Chevy, running a belt drive to time the cams. Gary said that is was for a Bonneville LSR car, but he didn't know what it was going into.
Gary seems like a guy who can embellish a story a little bit, but this story has to be at least mostly true.
Has anyone here seen a V4 Chevy running Subaru heads?
SteveM.

Might be possible. Some Subaru engines have 113mm (4.449") bore pitch, not that different from SBC at 4.400".

I had to look up the bore spacing myself. Based on those dimensions, it certainly seems plausible. Wondering if the customer might be a member here.

The midget guys have been cutting SBC in half for years. Arlen Ness and had some blocks cast in a V4 configuration so you wouldn't have to plate the front (looks like a mini SBC). Also now they make a V4 based on the LS engine http://www.hotrod.com/techarticles/engine/hrdp_1109_v4_motorcycle_engine/viewall.html Pete Ardema ended up with all the blocks when the project was over and yes, he put Subaru heads on it. By the way he also welded 2 Subaru heads together for his V4 engine that set all the records before the rules were changed. Tony Subaru head for a Modal A block  |

Innovative and fascinating stuff. Those Subaru heads must flow very well. It's also kind of funny the way that 2 V4 engines can be discussed so readily, both using Subaru heads, one inline (Vintage 4) with 2 welded Subaru heads, and in a V-4 (90 degree) configuration with separate Subaru heads.

Tony, has Pete rebuilt and replaced all of his stuff since the fires a few years ago? Always loved reading about his crazy combos!
