421 Cammed 172
the seem pretty consistent to me! its my magic hands
What could i see from the 421's Fred seeing as your magic hands would be dropping them in??
Its going in this coming week fella
On a stock engine you'll probably get more power with 421's but the headline costs will be more.
You wont find many on here who will recommend you Pipers with them being re-grinds. I can only praise them as my motor ran very well with them.

I can get a set of 2nd hand 421's for the same price as the piper re-grinds.
I think I may have just decided

421s give similar peak numbers to 428s, but with a much better midrange. FAR less peaky
