New the the forums... awesome to know that there is a society for the 420a's I just got an email from Darren King over at FFWDCONNECTION.COM They make performance cams that rival HKS... He's offered to grind a set of .272 cams for the 420a if we order 4 or more. Any takers?

Sorry about the slow response... been helping a buddy tune an 06 mazdaspeed 6...
$300 for the .272 cams
Warrantied for a year... who the hell can beat that??? The only thing is... I gotta find out if I can run the hyper flat tops from dsm graveyard, stock rods/crank and get their bee-hive valve springs setup... I've seen a few people run 272's with stock valve train stuff....scares me >.<

Yes... He's agreed to grind a set of .272s.... Only because there's not enough demand for the stage 1 420a cams... I would think that stage 1 would be a waist of time... I was trying to talk him into doing a set of 280s.. But I don't think that there would be enough demand... He usually only works on 4g motors...

Thats what I was thinking.....I remember looking at the numbers before. Crower 3 cams are 254/250 duration.

Crower not Brian Crower, two different people =) I didn't see what you had done to your car, but Crower 3's may be to aggressive for you, unless decently modded, may want to stay with Crower 2's.

I'm rebuilding a stock 420a... found a set of sealed power flat top hypers that I want to use. All motor no boost... probably keep the stock rods with this setup. I'll port and polish the heads (along with having a new valve job done). Installing a megasquirt II this weekend
I've got a spare engine/trans which is what I'm building before I drop it in...

Thank you... I didn't know that the 420a only had one head... I was thinking porting/polishing the ports.... the plural carried over to the head. It makes sense in my mind >.< Why are you so critical?

Haha, because (I figured out) Dougie is giving the numbers at the head of the valve. All the others numbers you see are at some point of the cam. I believe his basically match up to Crower 3's (though a little different I imagine)

I asked this question in another thread, but I never got a reply back yet... Can anyone with the Crower stage 3 cams tell me when the power starts to taper off in the rpm band?.. (Given that the head is also ported and polished)
Double check all your coolant and oil lines....., before you take off and see a cloud of smoke behind you!
