196-800 rebuild

My 196 block just got the ok from the machine shop and I have a few questions. This 196 is out of an 800, after tear down and magna flux my machine shop said I have a decent block.

1. Shop said cylinder walls are good and could be machined out .020, is it better to go bigger or is the .020 enough.

2. Pistons? I have a quote from Jeff at ihon for flat top pistons, its my understanding that if I use these I need to get a different head? If so which one is it and what do I need to do to it to make it work or make it better. Will the header I have work with the new head? If its too much hassle I can get another quote from him for dish pistons.

3. I sent my cam off to have a preformance re grind done, I understand there are a few durations to choose from, any ideas.

4. Budget is 2.5k, my quote from the machine shop is $850 for hone, bore, deck, grind, and balance. Im in 200 for the cam and 175 for the carb and close to 700 for the pistons, rings, ect. In short I have a few hundred left and I want to make sure im spending it doing the right things to get the most out of this motor.

I have a pertronics setup for this motor and a header, mr maben should have my carb if ups is taking care of business. The rig its going into is a 64 Scout 80, I have a t-18 four speed trans with transfer case with d44 front and rear running 33" tires. This is a daily driver-bar hopper rig no trails for this queen. Any ideas or help is greatly appricated.
Thanks
 
Jeff can get the correct piston. Make sure you ask for the style that came out of your 196. Take a picture of the head combustion chamber and I will tell you the correct style you need.

Was this a working running engine before you took it apart?

Unless you will be upping the compression and doing some porting stay close to stock duration or 202-204 intake duration max
 
Thanks Robert ill send it as soon as I can. I was told that the motor ran, I got it from a Scout store in ia, via or. It looked very rough when I got it but it turned over by hand, my machine shop was very supprised how good of shape the inside was.

The quote from the machine shop did include porting the heads. I dont know if that makes a difference on the cam.
Thanks

That will definitely require the "contoured" type of piston. They are available.

The open chamber design of the contoured cylinder head will flow better but with flat top pistons, yield a low compression ratio. Using the correct contoured piston will give you the best results.

From a porting stand point, the exhaust needs the most help. Intake work will yeild little to no improvment with out it.
