Hey guys I'm getting all my pieces together for my 408w build and I'm looking for information on where to notch the cylinders for clearance. I'm debating about putting it loosely together to find the areas but I was hoping for some experiences. I even tried that book on "How to build a stroker Ford" but no luck.
TIA
 
Theres a kit you can get where the bit goes up through the valve guide, you bolt the head on, then put a drill on and notch the piston. This puts the cutter right where the valve would make contact. I wouldn't recommend this if you already have the shortblock cleaned and assembled however, metal shavings everywhere. I'll try and look up who makes the kit and where you can get it.
 
Wait, you said cylinders, I was thinking pistons for P/V clearance. Sorry! I would say send it to a machinist, or I take it you want to do it yourself. Best way would be like you said, mock it all up and see where it's goina hit, if at all.

Could you post a link? Sounds like something I could use in my toolbox.

Install the crank rods and pistons and mark where the bolts would hit. THen take a die grinder to it.


You'll want .080" minimum, I usually go .100" Make sure you use a lot of lube so you don't mess th new bearings up, you may find you do not need to notch.

I've done a 408 using a 6.2 rod, 4" stroker in a 74 block that cleared fine.
 
Thanks guys for the replys. I guess I will have to mock it up and see. Sounds tedious putting it together, tearing it a part, grinding and then cleanup to mockup again.

Thanks Rick. That's my combo to with a 70 block. I hope it clears the first time. :D
 
I clearenced mine before taking the block to the machine shop by doing it the mock up way. Time consuming for sure, but definetly the best way to do it and it's fairly easy. I used some used bearing's I had laying around that were still good and lubed everything up inorder to not scratch up or mark the crank journals. In the end I still had the machine shop give the crank a quick polish just to be safe anyhow.
