I can't tell you guys how lucky I am to have this engine builder in my back yard . He just finished a stock 396/325 motor for my 69 Convertible I'm restoring it made 406hp and idled at 650 rpm. Everytime he dyno's one of my engines it's like seeing your new born child

Cant wait to see the results On 4.0 stroke and smaller builds, does the windage issue show up early in rpm's , or just 4.25" stuff and up does the issue really manifest itself? </div></div> I ran this engine to 6700 RPM with no windage issues, but I wouldn't run this pan on a longer stroke engine. |

"stock" as in stock cam, stock compression, stock manifolds? Impressive! |

Mark, no induction detail or cam specs? I know this will work well. Probably run faster then it should for the Hp of the engine too.

Mark, that the way I like them to look, innocent and mild. Then the thing runs like the wind. ANYONE can make a aftermarket run, it's these engine with nothing really special in them and run hard that surprises people.
Now if you didn't block the fuel pump drive, let the belt turn the waterpump, and used a "normal" distributor and not a crank trigger. It would be even more innocent.

Hopefully you can give us any insight on how to tell a 4 bolt block externally they used to have a 1" plug for oil cooler now as you can see thats not on this block, is there any other way to tell without pulling the pan? the side oil galley plugs used to be 1/4" vs 1/8"? sorry I dont mean to hijack your thread [img]<<GRAEMLIN_URL>>/crazy.gif[/img]
