I've done more than a dozen so I really enjoy it! This would be my first small block stroker tho'.

Pat, Jerry? Would either of you guys know which distributor gear to use with an X303 Ford Motorsport cam? I couldn't find the info on the oem site..

Mike - you need a steel (best wearing), bronze or 'plastic' gear for the steel 'letter' camshaft. The cast iron gear will not survive. You also need the Ford Racing steel camshaft retainer instead of the OEM cast version and, preferably all ARP bolting. Then, of course, if a mech. fuel pump, you need a longer drive pin (I have 22 extras if you need one as they are unobtanium from Ford) and a one piece eccentric plus that ARP bolt. All this from my Book of Lessons Recently Learned

Randy - I seem to add a chapter every time I even look at the engine

Another chapter for Mike - some double roller timing chain/gear assemblies for 302/5.0 Fords will come close or even hit the block - you need about .125 clearance

Thanks Dave! No sweat on the other "details" as the engine shop "should" / "better" have that covered. I was just looking on-line at distributors and it popped into my head that I may need to change the drive gear.

I had one of those "moments of vindication" yesterday.. I was second guessing myself in the decision to build a stroker since this motor was already all new. Well I went to the shop to check on progress yesterday and the machinest smiles at me and says "hey, ya gotta see this!" He shows me the conn.rods and 3 or 4 of them have a huge circular gouge in the bearing maybe 50 or 60 thous. deep! I looked at him and said what the _ _ _ _!... He shows me the crank and some of the journals have dents / burrs in them! We surmise that the kid that "overhauled" / assembled this motor had let the conn rod bolts ding up the journal and never cleaned up / polished those birdies! We also complained to each other as the shop that did the overbore laft a crappy finish and sadly the cylinders aren't straight! Not real terrible but, it should still be the same measurement top to bottom!

So when I left I felt REALLY GOOD that I made the right decision! Or maybe I got lucky for a change!

O U C H !!!

But with that stroker kit - those parts are now 'surplus'/scrap - luckily for you!!!!
But - remember ARP fasteners.

Well I got the engine back and "played" with it some tonite. I know that some "certain" folks feel that picture posting should be mandatory so I won't do anything to upset them!

Here's a couple of the short block.

Here's a few more.

What color are you going to paint it? Is this going in your hotrod or are you buying something else to put it in? Of course, answers to both of those questions will require more pictures!

and here's what it looks like at the end of today. Hey, IC2... empty your mailbox.. PM's can't through!

Awesome! I see you're building it for fuel economy......

I was listening to the Rolling Stones.... "Paint it Black!" It's for the 34. Hopefully I'll swap it this winter.

That flat rocks
