Wow when I posted on here I did not have my 493 built and its been in my 63 since June 2011. Here is what I used so far:

440 block .030 over and main studs
440Source kit with 4.15 crank and dished pistons
Indy EZ heads from Dwayne Porter at 10.6 comp....I decided to go with EZ heads in case I want to step it up more in the future.
Custom grind cam solid flat tappet from Dwayne Porter .585 & .592 that is 264 & 270 @ .050 on a 110 LSA and its in on a 106 ICL.
Hughes 1.6 roller rockers
Indy dual plane intake and an 850 DP
Mallory dist and MP ign
TTI 2" headers and a full X-pipe 3" exh


I actually have only put 7 passes on the eng with a 10.76 @ 124.49 best in my 3700 lb 63. It is a street car I drove to the track and it runs on 92 pump. I really think it will go faster with more carb as it wanted a ton of jet in the 850. Good luck with yours , Ron
