Crank is strong for the street, so is the factory rods (all are forged) and rod bolts. Stock pistons are a weakness though. true, except the later model hypereutectic pisto...

Re: NHRA Div III Finals - w/ FTF

UPDATE 2018:
I was number 38 on the 38 man team my home track selected to attend the 2018 Division finals. There were about 160 - 180 cars in my class, Super Pro.

I was able to win three rounds before falling in the fourth in a double breakout affair. Our team finished third out of 16 teams.

Re: FiTech (or other FI systems) used with boost.

Don't assume rods with a small chamfer will clear a large fillet radius. Check.
I always chamfer both sides in a rotary vise on a Bridgeport.
I've had them contact.
Also, be sure to check for proper side clearance on an off-the-shelf aftermarket rod. I've had "issues" with that too.

I do not think seat inserts are necessary. I also worry that if the head is cut then it may crack under the seat, particularly if there is any core shift.

The parent head material has been induction hardened around the seats in production.

OK, saving all the engineering-ese speak, what it means is the stock crank will crack at the #6 rod journal if left alone. If ground for a smaller diameter with a larger cheek radius it will live longer.

You can lighten the pistons without taking weight off the crank - and vice-versa - just be sure all weights of the piston are the same, and the crank is rebalanced.

Re: 300 Piston skirts

You may lighten it and you may reduce breakage, but the stock, non-hypereutectic pistons have a steel expansion strut cast into them and this is where the stress risers initiate cracking. But its an interesting thought. Many modern engines have far smaller skirts and live just fine. Try it and let u...
