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.

At this level of build I would be hunting thermal control.

I'd try to keep the heat out of things via ceramics and try to improve the transfer rate to remove the heat that makes it into the metal.

I'd detail the cooling passages through the head, remove all of the casting flash.

I'd research coatings to improve heat transfer, maybe use.

I'd finish the tins out tight, no air leaks, tight booties on everything.

I'd improve the cooling abilities as much as possible.

One thing that does help!

Tangerine Racing has a race car with a 4-5" duct through the cabin directly into the fan.

Like a raccoon Habitrail through the car!

Sadly, that wouldn't work for me either...
