Engine Build Ideas...PLEASE HELP.

You forgot a few things
Pushrods & rocker gear
Retainers & locks $65
Cam bearings and install $50
Recon rods and rod bolts $150
replacement valves 5-10ea
Press pistons on rods $50
magnaflux as required (crank, heads, block) $50
and there are plenty of incidentals that you need to buy as well.

Your right I sure did...
I added rings when they actually come in the kit along with Cam bearings.lol install cam bearings$40 [I install these my self as should every one else]IW
Locks $14 [something you should always replace]
Your price on the rods is roughly what it costs here $ 114 w/replacement bolts+ 40 to press pistons.
Is he gonna rev it past 6000rpm cause if I remember right my stock 340 ran 6000 all day [as it was advertised] and never broke a push rod or rocker so I would reuse these if the funds weren't there.
The idea with the valve was to reuse the exhausts and just upgrade to the 2.02 on the intake which was included in my list.
SO $2137 and you have a long block [which is the main objective]
after that it's pidly stuff, intake plugs, carb, wires ect.
