Re: Starting My 392 Poly Stroker



You'll definitely have an easier and cheaper time building a 440, and the power will come easier. I'm sticking with the poly as I want it to look pretty original and they are something different.

I gotta ask the question, since I am building a 62 max wedge clone, numbers mean nothing to me,but found a 68 HP 440 and putting a max wedge cross ram on it with newer ederbrock 750's, mainly because of cost compared to correct carbs,Is building any poly worth it or even a 413  compared to a 440,especially finding motorhome engines that can run circles around them, or is it the love to be different.not trying to be smart ,just grew up knowing cubes are cubes and 318 versus 440 and see the same money spent on rebuilds. I think I am missing something,please don't hate me LOL? thanks Russell

Bill,
 
Good pricing Bill!  The “H”series bearings are hardened rod bearings and I would also recommend them for your Stroker application.  The 4” crank puts a lot of stress on the rods and main caps so hardened rod bearings are good insurance.  A set of full-groove mains for your crank w/high volume oil pump is also recommended. 
 
The shop will have to clearance the rods to the block with a four inch stroke but the Poly requires only minor clearance and shop time should be no more than one hour.
 
What cam profile will you be running?  A 234@.050” duration HYD. is a very good profile for the Stroker, or the 244@.050” Solid Cam for most applications – this will yield approx. 400-420HP and 440-450ft. lbs. of Torque at low RPM levels (3400 & 5300 respectively) and produce extremely high & flat average numbers.

Well, I'm dropping off my block to begin the 392 poly Stroker project on Wednesday. Found a local machine shop with a good reputation that's reasonable priced. Hot tank, magnaflux boring & honing will cost me ~$260, clearancing the block to my rotating assembly $80-120, Install cam bearings $60, assemble the short block $250. so all work to get the short block in shape will be ~$630...not too bad I guess.

He suggested getting "H" series bearings...what's the significance of these series bearings? He was talking about clearance for crank radius or something but there was alot of noise in the background.
