Alex, while checking the NHRA stocker piston list in the ND, I noticed that only 1 piston is legal for my 85 Mustang 5.0 HO, the TRW L2482. I also noticed that this piston is legal for a 63-68 289, however the 289 has 4 other approved pistons to chose from.Would it not seem logical that all 5 pistons should be OK in my 302? Is this just an oversight on NHRA`s end? Also have you ever had a later 302 block sonic checked? I have a standard bore 85 HO block, & was wondering if it can go .060 without filling the water jackets. (with my bulk,I`d prefer to not hang an extra 25 pounds on the nose) Or do you think I should stick to .030? I wonder if an extra 5 or 6 cubes is worth the weight of the block filler.

No, he should be back Monday, or so.

He's racing in Tenn.

I was just getting to this one Rory. The L-2482 is a late design generic dished 4 relief 289/302 piston. The other 289 pistons are higher compression and are not acceptable for 302's. You can safely go .060 over with a late block. We do it all of the time and have had no failures on race or S&S engines. We do fill ALL of our race blocks though. I don't sonic check blocks anymore as the process cost is more than boring. We give them a good cleaning and eyeball the hell out of them first. You can usually spot an off center block pretty easy.

Thanks Alex, welcome back from "SUNNY" Tennessee. How high up do you fill a 289-302 block? How much weight did it add. I`ve only ever filled 1 block before (428 FE) & I filled to the bottom of the water pump holes on that. I`m thinking of building the 1rst engine Std. with the OE forged pistons the engine came with if I come up with a nice Std. block. Probably won`t get too fancy until the 2nd build up. Obviously won`t fill the Std. bore due to the bores getting pushed around from the filler. Thanks

JD, Kuntz & co. in Arkadelphia Arkansas does 85% of our machine work. The other 15% is done locally by MPG in Skokie IL. Rory, we fill the block up to the water pump holes. the motor in our P/SA car is a "stock" 94K 5.0 HO short block and it's currently going .41 under the index without even pushing it.

Oh Yeah Rory, I forgot. About 20 lbs. gets added to a little motor by filling it.
