Nice. I saw some flow numbers for a 2.5 stroker head with 2.02 and 1.6. Intake number was 300 cfm. Didn't give any lift or other numbers. I have heard that the 2.5 is based on the 4.0 head. Man I miss this stuff.

Are those KB's. That looks like a nice piston. Gas expansion cut on the ring land and the pin is not in the oil ring. Full quench band too. Been waiting for you to post more goodies.

It's there ICON brand.
It's a forged piston not that other crap with the KB name.

I have used this brand a few times they seem fine. I will put then at the same level as like probe. But for a shelf piston and for no more than what I need them for there more then nice enough.

I'm work out doing another that looks like I'm going to offset grind the crank .090 and use a 2in small G Chevy rod at 6in long and bore it 4in.

The only thing is, looks like im going to have to put 6 flange sleeves in it.

What sucks about this 4.6 I'm trying to build now. Is I keep selling my blocks I have. But I rather have the cash. Still got to make a living.

Two things I dont like about the pistons is they don't have pressure oiled pins and they use the 5/64 rings instead of the 1.5

Camshaft Question

Hi, I have a 1993 Jeep XJ is 4.0 High Output 242, I'm rebuilding the engine, I must replace the camshaft, I was seeing the Mellings MC809, they claim that is a stock fit for my application, but looking pictures of the camshaft online it has an extra lobe between #3 and #4 valves I assume is for mechanical fuel pump on carburated engines, Can I use this camshaft???
Thanks

sorry for so late. But yes, that's for a fuel pump. There is only two cam cores to start with.
Yes it works just fine
