Re: Clifford dual Weber 38 set up

Good plan:) but it's only the manifold. No Webers...sadly. But from the sounds of things, I'm on the hunt for some 2100 carbs. There are some cheapo carbs on EBay that are knock offs. Not sure if anyone has tried them. Don't want to spend good money on garbage, but if they are good, I'd like to know...

Re: EBay forged pistons

Thanks pmuller Absolutely! I have three straight forward choices, reconfigured u-flow, cross-flow wedge, and cross-flow hemi. The tough ones are single or double overhead cam. Gear adaptation to clear the waterpump, and mounting to a push rod casting makes the latter choice an interesting challenge....

Re: Clifford dual Weber 38 set up

Thanks Bubba!
The intake manifold for the Webers is a dual 2v, if I'm not mistaken. I'm worried about the airflow through the adapter (which allows the Autolite to mount to the Weber plenum) into the plenum. I guess some grinding is in store... :D

wet sleeves

Has anyone tried wet-sleeving a 300? I am curious to see if it's possible to get a 4.25" bore, using 454 pistons. From what I understand, the bore linings have to be CNC machined out. I need to research the viability on the 300. It would be an extra 18ci. Not sure it's worth the trouble.
Cheers

I appreciate your patience. I suppose the harmonic balancer is designed for the original crank. As well, the engineers didn't originally fully counterweight it for a reason. I contacted the maker of Ron Coon's crank, which was mentioned above. He said they had no vibration issues at all, but never r...

Nice numbers. Although not everyone is inclined to proceed this way, I think it should be every hot rodder's duty to buy a grinder, get some junkyard heads and start playing. All this CNC stuff is for high dollar motors. We are a different breed, believing a low revving tow truck motor is worth play...
