Fred's 2375 Rebuild Thread Options

[A softball question for the Ninja and/or others]

This is the cam card that came with my 2357 engine, which was originally built by Rimco/Fat (long block) a few years ago. Can someone explain why with an intake/exhaust of 448, the lift was only set to 327 degrees? I'm about to rebuild my motor and a lot of focus will be directed at piston "deck clearance" and the valve train geometry that wasn't set correctly. Thanks.

Thanks to @densible1 and @burton73 for the photos. Very interesting to see one of these old RAT engines. I'm still studying all these photos. BTW, I modified my windage tray but with four 1/2" drain holes but Jake's mod is a lot larger. I also plan to do the RMS mod this time around, too (IMG:style_emoticons/default/idea.gif)

@burton73 - you said it was a 2270. Pistons look larger than 96mm and the CB rods are 5.4". Do you recall the crank size?

Mark says 96MM on pistons and we know nothing on the crank. This eng was in one of Oscars cars at one time. The crank wasn't very pretty as some custom cranks I have seen on the web for different cars. Not sure that matters just something I noticed.
