Hey guys first post here, I've got a very very well cared for '46 COE. Turns out it's not the original 216 (of course) and its a 235 with a LAS prefix. So that puts it as a powerglide/power steering motor? Then the head code is 3701887. And that's the head from a powerglide car right? Doesn't it have bigger valves or something? Anyhow, I'm almost thinking is this a 'vette motor? As the LAS code is identified in by this website in the same spot as some corvette stuff. Sounds like perhaps a corvette block rebuilt with a regular head? Anyhow it's all fun I love working on this thing. Haven't even snapped a bolt off yet. Oh yeah and the valves in these heads? If you ever need an exhaust valve, the ones from a '95 TBI 350 are IDENTICAL. hahaha! Anyhow, any tips on what I've got?
