Gary Isbell ran low 11 second quarter mile times in his Modified Production Maverick back in the mid-1970's with a 300 engine in it. Using modern porting and cylinder head techniques we have now in the 21st century, a stock production cylinder head still offers more than enough potential for what pe...

Re: Rear Main Seal

Yes on the sealer! Its common practice to rotate the upper and lower halves of the seal so the parting line of the block and cap is offset from the parting line of the seal halves to reduce the chance of leaks. Apply a thin dab of sealer at the parting lines of the seal and this should also seal the...

Re: Front timing cover dowel pins

The Ford 300 doesn't have dowels in the front of the block, there is only bolt holes. You have to let the timing cover self center with the balancer in place and tighten the timing cover bolts before you tighten the oil pan or it will move it off-center and leak.

The two different materials distort the block differently, so aluminum torque plates need to be used with aluminum heads and steel or iron torque plates with cast iron heads, or its like not using a torque plate at all if you mix them up.

No, you'll have to at least pull the valve cover on the #1 cylinder side and install a degree wheel. Of course, finding true TDC is going to be more challenging, but necessary to confirm true cam timing events with any accuracy.

The factory timing sets and factory replacement aftermarket sets were actually retarded, not the cam grind. So installing the cam straight up with a high performance timing set like the Cloyes should advance it 4° over the stock timing set. But you still need to check it to verify as always.
