Got offered another engine

Upgrade to a 350…? What engine are you running now…?

 

I assume it’s a BC IV. There is no need for Teflon parts. It’ll easily go 400. If you ditch that low flow cooling you can easily run 500. The low flow doesn’t do well with higher HP

 

Ok, I guess your engine is having problems?

 

I’m not running 500….. anymore.

 

I’d still be trying to get rid of the low flow, but lots of 400’s were built with low flow. Guys having problems keeping them cool have been monkeying with the pump. But stock 400 settings aren’t anything to be scared of

 

Lot of that is 3.55 gears on tall rubber with a little motor. It’s probably better suited to 4.10’s or 3.90’s

 

I run a Big Cam / 13 / 3:70 / tall 24.5, out pulls the 365 Big Cam / 9 / 3:55 / 24.5 tall in the 88 K100 I drove for H&W years ago….
