2f Engine for myblue

[72myblue]

I'm pulling my '72 FJ40 out of the side yard and updating it for modern highways. I found a 2F engine and I feel no ridge in the cylinder so I lucked out. I've decided to send the cam to Delta for a 250 grind. I don't want to build a Hot Rod but I would certainly welcome any advice you folks might offer that would beef the 2F up a little. Also, for quieter running. For sure I want to get US or Japanese parts and I'm not sure where to find them. Sam+--

If I were to build a 2F....

Larger valves
Proper valve grind
Heavier springs
Cam
At least get the intake and exhaust manifolds to match the ports.
Have everything in the bottom end balanced.
Maybe bump the compression up a hair. You don't want something that will only run on race gas, but it'll run on just about anything flammable out of the box.

And a sniper efi.

I'd probably just call Mosley.

Did you do the Delta 250 cam grind? I am thinking of that myself. From what I read and understand, seems like it keeps the torque close to the 1800 rpm range (overlap from 31 vs 32) and changes the duration so that get more rpm/umph above 3300 rpm.

There is a lot of driving here in fly-over country. My thought is the 250 grind by Delta would help on the upper end of the MPH for daily driving, yet retain the the torque for when off road.

I see RV grinds - but that seems to be more for serious off roading.

Thoughts/experiences with Delta's 250S grind?
