Default Rebuilding a 5.7 vortec, farmer rebuild parts question

Okay I want to rebuild this 350 and it needs a new roller cam lifters valve springs and rings and main bearings and rod bearings. where can I locate the best price parts for a farmer rebuild that I want to do on this 350 to get the most that I can out of this snotty small block. Plan on rebuilding the vortec heads and using the stock EFI throttle body for now. Can't afford to go Gonzo first build. This 5.7 going in a 20' cig I'm restoring.

Pull it apart and if your unable to do it find a machine shop that can advise what need to be replaced or turned. Doing a standard rebuild is not that expensive

How many hours on it ? Looks like it is raw water cooled, will most likely need cylinder heads They get corroded around the big water passages to the point of no return. New heads are not that expensive. Put a set of stainless intake valves in them. The stock exhausts are fine. Your machine shop should be able to source you a rebuild kit with all the parts you need for a decent price. I know I can generally match most of the online prices and that way you make sure you are getting the correct stuff.

Main thing is like Dodge said you need to get it apart first and see what it needs.

So no inconel valves for exhaust, I thought Marine engines always had them. Hmmm ok.
yes I'm buying new heads and cam- lifters. Shortblock I'm rebuilding that part at home. Needs no boring, just rering and bearings, pump.
Biggest? Is cam specs, anybody?. Stock cam just isn't enough for headers I plan to buy. Hardin marine marine stainless.

Cylinders may look like they don't need boring, but strongly suggest boring, pistons are not that much more

What is your Hp target? stock exhaust manifolds are good up to 400hp and more. With hotter cams you can weld stainless extension pipes to the riser to avoin reversion.
