Strongest as in power or strongest in block/rotating assembly strength?
Brian at
www.adperformance.com can sell you everything you need, from the block to the bearings, lifters to the heads, etc...
I'll try to answer both questions:
Start with a dart block, either sportsman or eagle and get a nice forged 347 stroker kit. Block runs around 1500-2000 and the kits start around 1300.
I'd go with some AFR 205's, Systemax (ported to match), custom cam (maybe higher rev setup so go with a larger intake, maybe the vic. series), 36-42lb injectors that NEED to be tuned, 75mm TB, Hooker 1 3/4" Longtubes...80mm MAF and a 3.5" or 4" powerpipe.
Of course you will need the little things like Roller Rockers, correct length pushrod, billet timing chain...
For the 'topend parts' that I just listed, you can contact Ed Curtis, custom cam designer, at
www.flowtechinduction.com. He can set you up...
Good Luck!
