Hot Rods - Rebuilding crank

[Capone]

I've been reading about crank pressure, and how much it can handle. As I stated above, I believe my crank is pretty much at the end of its potential, and I'm looking for an upgrade.. since I'm going to bump timing soon.

 

I found some hot rod connecting rods, for 80$ a piece;

If I replace stock rods with these, then have the crank welded, will it handle 17-18 cc domes with advanced timing? around 200psi of compression?

I'd ditch the stock crank if I were you. Its really a cheap design that is bound to fail - welded or not. If you want to build a reliable machine, get a wiseco crank and don't skimp.

dont know if this would interest you, but i hae a weisco crank, with hot rods on it, new bearings, stock stroke, if your interested for sale 225 shipped.

I know just as many people with aftermarket cranks that have failed as stock cranks. My 1988 stock welded crank is still doing great, many mods including porting, head work, timing advance,34MM carbs,etc, since 1989.

Same here. I feel a lot of stuff gets a bad rap for just plain ole lack of care, tuning, maintenance. People think if it is an aftermarket piece it has to be better and if it fails, something else caused it. If a stock unit fails, it's because it was designed poorly. Not always the case.

I'm not saying that an aftermarket crank is impervious to damage. But if you blow a stock crank, even rebuilding it won't solve all your problems since you can't replace the pins. If you blow an aftermarket, you can rebuild it from the ground up so that it's as good as new. Also, most of the aftermarket cranks I've seen have tighter clearances than the stockers.

I really don't think is cost effective to rebuild either a stock crank or aftermarket cranks (exceptions would be a billet crank like twister). Any time you install a crank into a Banshee, it is a very good idea to have it welded, especially if you have or plan to have mods.

 

The after market cranks like Vito's and Wiseco need the pins welded on both ends. The stock Banshee cranks only need to be welded on the out side halves.

 

I don't feel it's a good idea to rebuild a welded crank with the exception of the billet crank, as cutting the welds and pressing them a part degrades the stock and Wiseco cast steel parts.

Ditto, just order the wiseco crank with hot rods, welded , trued, lasts forever.
