Personally, I'd rather Have the 350 H.O. with a XE274 cam swap and uprgraded valve springs. THAT (in 350cid) would perform aswell if not better than that, for less money.

The 383 is about $4600.... while the big blocks 620 HP and 720HP are about 15,000 and 16,000 respectively

You are posatively insane to pay $4600 for a 425hp 383. I could build that power and reliable of a 383 for $2500.

Oh, I'm sure anyone with a good mechanical backround could built one for cheap..... but I'm what they call...... DUMB when it comes to this kinda stuff. Throw labour on top of the parts and I figer it's a pretty good deal for not knowing much. I could probly throw it in a truck but that would still take some learning for me.

yuo should give ProStock in Edmonton a call i'll bet they can give a good price and since your pretty close you won't have to pay all that shipping and put the money towards other parts.

Check out www.larrysperformance.com. Thay quoted me a 383 shortblock running 10:1 forged TRW pistons fully assembled, balanced and blue printed shipped to my house for $1500. Now you take that 383, have larry's throw some big ol' afr heads on there and a holley double pumper, you now have a motor with about 100 hp/ 100 ft lb more power for less that that 4600. Can't beat that!
