port and polish

[pearl111]

If I port and polish a predator 212 hemi I'm sure the motor will perform much better but my question is do I gain any more horse power?

Just a tad, you may not notice it by the seat of yer pants. Generally more extreme porting/polishing jobs accompany an aggressive cam and a big carb, but yes, there are small gains to be had by P&P'ing.

If the gains are that little for me I see no reason to atemp a port and polish.

Yeah, unless you're doing a really advanced build, it's usually better not to, given that it means risking screwing something up.
