I believe the 68 to 70 350 2bbl also is the same, as long as it is in useable condition and willing to ship to Canada. PM me with your price and pics. Thanks.

Rod I have for certain; will have to check on piston. Thanks, Bob.

Have most every type of olds pistons & rods..& tooling to add rods /subtract pistons
took thiis 4655/350 foto other day figurin it would be of use

Hi comp 455 piston & rod & H/C 350 piston without rod
have other pistins available these just handy examples

If you have a part # I can see if I have it nos.

Good question. I wonder if Joe P on here would know the part number or where to find it. The piston itself may be fine but I won't know till I pull it apart. The rod is not, it is bent. I hydrolocked it using a combustion chamber cleaner which does work to gain compression. I gained 15 psi on the cylinder with the bent rod and 25 on the other. I have done this many times and finally got burnt. Plus heating so the pin can be pressed out, might make the piston unuseable to install again. This is a short term motor, not going to have a perfect balance. The 330 crank I plan on installing was balanced for stock rods with the discontinued 18cc dish Speed Pro forged pistons. It will only see around 5000 rpm. Basically, new rings, bearings and gaskets with the 204/214 to replace the failing custom 214/214 cam Cutlassefi ground for me.

Anyone got one lying around?

Indeed

Not sure what is different but part book has code A/B, C or D. Which do you need?

I made a fixture to press pins out of rods cold. Just wondering if this is making rods or pistons unuseable.

rocketscientis

piston must be supported where pin comes out
Of piston
Wil post pix of toolin but have to take them ..

That is what my fixture does. It supports the piston while the pin is pressed out of the rod.

What is the procedure to R and R a press fit connecting rod? It is supposed to be red hot or the oil starts burning them pressed out? I may just pick up one reconditioned rod. I am not paying hundreds of dollars for weak factory junk. I may as well spend $1000 and get massively improved modern forged pistons and rods for anything over a couple of hundred dollars. Weight would only need to be removed on the 330 crank, balanced for Speedpro pistons and stock rods. Pretty sure it would clean up at the 4.065" hone to oversize. I have cam bearings, so just install, deck clean and measure journals, pretty sure the .020" and .010" the crank is good, journals are smooth. Anyone have a single piston and rod that is usable? This is only a stop gap engine but I don't want to drive it as a ticking, gutless low oil pressure wonder this next Summer.

May have entire assembly available if that helps
clean parts & warm rod & light oil could help but not required
Air / hydrolic press is nice too
Believe red hot would rehnder rod condition unusable. Lost oil pressure on 425 & even with kill switch , rods & crank were sickening color & would not reuse & they were no where near red hot
