How about a 49-54 chevy pickup. Lots of room under the hood. I'm putting a 292 in mine with a 4-71 blower. There are lots of parts available in original and speed parts unless you go like me but I'm far from normal.

Mick53,
That style of truck is beautiful. I have a 65 C10 and C20. They have a similar issue, in the fact, that running with no hood doesn't really show off the engine like the roadsters of the 20s and 30s or MGTD with the hood and side panels removed.
Regards,
Rick
