(These are only slightly higher cost than the pistons in the kit above, so I will ignore this added cost)

Images, please ask if you need to see any other angles. I will add them to this thread.

 

Quick shot of the cam bearings.

 

Side note, I have a great high quality custom grind blower cam (specs will be in separate post, hydrolic retrofit roller lifters, pushrods and Trickflow 1.5 roller rockers also for sale.

 

what cr?

Looking for a nice replacement for gerrutcamaro who's block got wrecked by an idiot (if you care, check his build thread, the carnage is in there)

 

Cr depends on heads.

I was around 9.5:1 with my 64cc heads and MLS head gasket.

 

I know it depends on heads. 9.5 is a little low for na with big cam..

How much cc dish do the pistons have?

 

The part# on the piston shows -18cc and bore size of 4.060, if it's a 3.75" stroke the it's a 388, did you use the diamond ring kit?

 

I didn't assemble the motor. I would have to ask the builder what ring kit was used.

I spent top dollar to get this motor to hold up to the boost I was going to throw at it.

I still have the F1 Procharger and 12 rib pulley I was going to run. (also for sale).

As the short block sits the cam is out of it.
I figure if anyone buys this setup it would be great for boost. Or maybe a small combustion chamber head that bump the CR back up to a NA happy zone.

I will post a "for sale" thread now for the cam so you can all see the specs and see if you would want to take that with the motor.

 

First potential buyer driving 3 hrs to come take a look next Saturday.

Motor is also posted on Craigslist.

 

Sold!
