Pushrod tubes with Stroker Cranks

[tornik550]

I just ran into a small problem. I have a 78mm stroker crankshaft, 5.7" rods and appropriate pistons. I went with this setup because I was looking more power and a close to stock rod ratio. I knew that I would most likely have to use cylinder shims but I did not consider that I would need longer pushrods and tubes. The rods are no problem but I cannot find any adjustable or extended type 4 pushrod tubes. I can find extendable t1 tubes but I am pretty sure these will not fit. Does anybody know of a solution to this problem? Can I use tubes from a different model or does anybody know where I can find adjustable or extended t4 tubes?

Thanks again for your help,
Steve

If you have some old dented-up tubes lying around, there's a poor-man's solution too - cut the ends off them to make your own shims. Having two O-rings instead of one doesn't hurt any, either.

FAT has some longer billet ally tubes available that will work on an engine that is up to about .5" wider per side. Very nice quality and worked on a customer's engine quite well. Not cheap though.
