273 302 318 340 build
sale off your 318s,..buy the 340,...youll love your self for it later on!!!
LOL, Im definitely tempted. Forged crank turned 20/20. New rod bearings/main bearings/cam bearings, moly rings none installed. .030 over piston. Engine is completely apart for inspection. No pump no pan. As far as I know lol(so far) all I need to purchase is
oil pan
HV pump
gaskets
balancer(maybe)
Stall converter(recommendations??) I was told 2800 would be good with my 3:23 gears.
I have cam/lifters, X heads, LD340, carb and Hipo manifolds. And a rebuilt 904.
Now what I found out piston wise with 318. I spoke with both FM tech and Summit tech for piston options. FM tech (great guys!) stated the 285AP30 is the only option SO FAR!

1.72" comp height, so its stock, 9.2:1. Using 302's will raise it a bit. The 285's have 4 valve reliefs, so a loss there too. I havent crunched #'s on it yet. I looked on Summit site and it has the pistons listed as press fit.... WRONG, they are both, press or floaters.
I asked the machinist about using the smaller rods and bushing the small end. He said that he doesnt recommend it when you convert them to press fit. He said its fine if you go floating, but said to not do it for press fit.
He still said I could still go with cast crank(up to 400 hp) and heavier rods and not have to worry about balancing. That opens up a wider piston option, but in reality press fits were pretty much the same price, just wider selection(and bigger compression height).
I was hoping/trying to keep assemblies "matched" as once the engine is built I want to sell the other short block(tired of toe stubbin').
Decisions decisions..
