I used these 440Source dished pistons in my 440 based 493 I built for my 63. But I used the Indy EZ head since I got a very good deal on them from Dwayne Porter and it was worth the extra few hundred to me as I was going to use Eddy RPM heads. But actually I was going to have the RPM's CNC'd and that added enough that the EZ heads I got from Dwayne ended up costing less as I just had Dwayne work my EZ heads some and they were cheaper then CNC'd RPM's as the CNC adds like 1k to the price. But the EZ heads are 75cc's and after I used these dished pistons that came out about .007 down in the cyl I was at about 10.0 so Dwayne cut the EZ heads to 70cc's as I came out at 10.6 comp right where I wanted with my setup as I run it on 92 pump. Dwayne Porter also speced me a solid flat tappet I run thats 264 & 270 @ .050 with .585 & .592 lift. Has a 110 LSA and I have it in on a 106 ICL. I told him I wanted a cam with some rump rump in the idle and I wanted to make some good power since I run on 92 pump and run it through the full exh system. But with EZ heads and at 10.6 comp and .046 quench it runs good on 92 pump as I have run 37 total timing all in by 1800 rpm with no ping at all. The intake valve closes at 58 degrees ABDC @ .050 and I do use Hughes 1.6 roller tip rockers for .624 and .632 actual lift. I use the Indy dual plane intake with an 850 Holley DP as its just the basic DP and nothing special. But it works nice for me as my 63 is mostly a driver as the last few years I have only got to the track once a year but I have it out every weekend from March to November weather permitting. My stroker kit is a 440Source kit with the 4.15 crank and the I beam .990 pin rods. It has been in my 63 since June 2011 and has not given me any problems at all. The piston pins were a little tight in the rods and I just sized the rod bushings a tad to get the fit I liked. Nothing else needed any major work as I did some touch up on some parts but nothing much as I have no complaints with the 440Source parts. I drive it to the track most of the time unless I go to a track real far from home then I try to have a tow lined up in case I break but its always driven home and has run 10.70's so far at just over 3700 lbs. My brother has used 440Source kits also with good luck and he also used a Muscle Motor kit in one of his engines with Icon pistons and an Eagle crank with no problems and good luck also. Thought the info might be useful for you to hear about. Anyway good luck with yours. Ron

We hadn't discussed camshafts yet. Just trying to be prepared and have a good idea of what I'd like.
