the seem pretty consistent to me! its my magic hands
Have you had your timing/power issues sorted yet Andyman?
I'm torn between 421's & Pipers and times running out!
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.

What could i see from the 421's Fred seeing as your magic hands would be dropping them in??
