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.

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. ------------------
