Assuming my role as the village idiot and the object of cautionary tales, I’ve got some experience here (most of it bad). I’ve had just about every permutation of Type 1 engine from a bottom feeding 1776 to a 200 hp 2332 sitting in the back of the car. There are plenty of avenues to dork this up, and because I’m hardheaded, I’ve headed down most of them before turning around.
I’ve presently got a 2276 dry-sumped and twin-plugged (for extra complexity’s sake). It’s kinda’ cool in a “what’s he smoking?” sort of way— but for my money, a 2110 with good heads, a W120 with 40s, and a 1-1/2” 4 into 1 header is the Goldilocks-zone.
1-1/2” heater boxes are widely available and EMPI now has 1-5/8 boxes, so I wouldn’t let stock boxes limit me in any way. I’d get a remote oil cooler with a bypass thermostat and a fan switch. There’s room to get fancier if you want, but this is by far the most bang for the buck.
That’s my opinion, and my wife tells me I assume that everybody is entitled to it.
