I'm looking at 3 different stroker kits, a 393, 408 and a 418 all 3 use 6.2" forged H beam rods, forged crank, and forged pistons. The rod ratios are 1.55 for the 393& 408 and 1.51 for the 418. The price is only $100 more for ea larger kit. So with the 418 only $200 more than the 393 the choice looks pretty simple! BUT.... Will I run into expensive machining and clearancing problems? If the 393w is a drop in affair and the 408 requires an expensive trip the the machine shop I might go with the shorter stroke and turn the rpms up instead. What do you think? SteveW

Well I happen to know one guy who is running a 410 stroker and he turns his 7600.  Thats a little more than even I probably would (yeah, right  ) and it runs high 5.70's in the 1/8. Another guy with a 393w only shifts his at 6400 and his car runs 6.70's consistently (both guys run a 'glide). The 5.70 motor has a billet crank, Victor heads, a roller and a toilet on top. The other has good stuff too, but no to the same degree. So in my opinion, rpm capability even in the strokers is just like everything else, the better the parts, the more rpm you can turn. (personally, I would build the 393 just for the better rod stroke ratio and the fact it should be easier on the block over yrs of running) [This message has been edited by kid vishus (edited 02-28-2002).]

KV,Could you ask your buddies if they ran into clearance problems with the 4.0" or 4.1" strokes in the 351w blocks?
The block is fairly fresh +.030 and I'd like to hone it and drop the balanced rotating assly in. Then put a pair of cnc'd Vic Jr heads on top and a sfi balancer on the crank and call it good.  Of course topped w/a Vic Jr intake and 850 dp'r.  SteveW

A buddy of mine recently put together a 426W. He had to clearance the bottoms of the cylinder bores...maybe around 1/8" to 1/4"... and die grind around the flange area where the oil pump bolts on. ------------------

Steve,
As said before, clearancing the block and cylinders is not rocket science. An air die grinder with a carbide cutter does a neat job. Just don't carried away.Its the initial idea of cutting on a good block. Been there and done it on the 347. Mike

Thanks guys!I'm up for grinding on not machined areas of the block. If that's all there is to it I'm ready. Let's get that 408 ordered and button it up! SteveW Next ? is which solid cam for the combo? No solid rollers please! Just a suitable solid flat tappet cam to match a 408w w/ Vic Jr stage II cnc ported heads and around 11-1 compression ratio. I want it to run "retarded" on pump gas, and balls out of race gas. Any ideas? SteveW

Steve, before you order it remember one thing...........THE ONLY THING BETTER THAN CUBIC INCHES......IS MORE CUBIC INCHES!
Cam selection as follows:
Comp 35-640-5 aka 290B-6 255/266 .576/.570 @106. This is a bad motor scooter with a 351 FO. Same as the 31-640-5 except for the FO.
Rock and roll! ------------------
