Questions on 344/349 build.

Alrighty. I require information before I commit to this.

I'm saving money and specing parts for a 318 build. I'll be running it against my buddy, a long-time chevy-builder, running 355's and 327's and we'll be primarily running in the 1/8th. I will however, be driving this thing very regularly. (My opponent will be driving his as well.)

I realize that a 360 would build more power for fewer dollars, but everything, particularly basic rebuild stuff is more expensive for some reason.

This has led me to the idea of building a 344/349 stroker, putting a 360 crank with the mains turned down in a 318 block, running an open chamber smog head, and running 318 pistons to put the piston just a smidge past zero deck. (.035 with 1.72 compression distance pistons)

I've been playing with desktop dyno, And with the parameters set as best I can, I should get 10.5 compression with 71cc 360 heads. Various cams put the motor making up to 430hp@6k/422tq@4500 There's no way I'd go with that much though, probably something that puts it closer to 350-375 horse.

My questions:

Where can I get floating Wrist pins for the 318? and are they cheaper than getting pistons pressed into the rods? I'm going to try and find an earlier engine that already has the floating pins, but if I can't, I really don't want to have to spend even MORE money at the machine shop.

Can anyone link me to a good rundown of the various heads? I can find bits and pieces, but I can't find something that'll let me compare the heads side-by-side, not to mention I find a bit of conflicting info. Valve sizes, what they came on, and chamber cc's in particular.

Furthermore, I'll be junkyard hopping for many of my major engine parts, Looking in trucks for heads and cranks. Are all pre-magnum 360 heads open chamber, or did some of them have closed chamber fast-burn heads? Are any 318 heads I'm likely to come across open chamber?

Is there anything else about the 360 crank that won't let it be put in the 318 besides the main sizes and getting it balanced? Any funny bolt pattern differences or the like?

Has anyone tried Rhodes Lifters? The ones that bleed down and reduce your lift and duration at low rpm, then restore it at high rpm? I'm considering a set.

Thanks y'all.
