Re: [Amc-list] AMC V8 Stroker Calculations

[Davis Martin <martin-davis@xxxxxxxxxxxxx>]

As for the 342 why bother when you can just use a 343 with 10.2;1 comp? I don't think you would get enough clearance on the cylinders for the rod throw either.
   As for the 435 .. I seem to recall that the most stroke you can get off a 390 or 401 crank is 3.85?  
   and that's alot of money to throw into a 360 block. But JMHO

  Hey guys,
I ran a couple of storker combinations through the calculator and came up with some interesting combinations to build.

342? STROKER (304 block & 390 crank)
Offset grind the 390 crank for a 2.10? Chevy rod journal, which allows a 3.782? stroke
Run off the shelf Chevy 5.7? H-beam rod (I Noticed that SBC rods are narrower than 390?s, so a Chevy H-beam 6-cylinder rod could be used, it?s slightly wider than 390 rod width and has a 2.0? journal).
Off the shelf 0.060? over (stock is 3.736?) Keith Black 305 Chevy piston (1.56? pin height & 5.5 CC valve reliefs).
With my current deck height (.010? milled), I get a .002? deck clearance (would be 0.012? on stock 70+ block).
With my current 62cc 304 heads (ported and polished ? SBC valves), it comes to 9.94:1 compression.
It can also run their 16 cc dished 305 piston, to get 9.6:1 compression. 


435? STROKER (360 block & 390 crank)
Offset grind the 390 crank for a 2.00? Chevy Rod Journal, to a 4.07? stroke.
Run off the shelf KB Chevy 400 pistons at STD bore 4.125? (1.133? pin height & 22 cc D-dish).
Run off the shelf 5.7? H-beam rods for Chevy 6-cylinder (wide big end rod)
Comes out to 9.75:1 compression and 0.030? deck clearance.
It can run an 18cc D-dish piston to achieve 10.1:1 compression


So, what do you think about these combinations?


Sincerely,
Greg Taylor :) <><
