Paul, you seem to be so knowledable about these 429 ford engines, (I've read several of your answers to questions). I will go further into detail about my engine. It is a 1968 Thunderjet 429 and it was bored .030 (thirty thousands) and new forged aluminum pistens with a compression ratio of 11.39:1, speed pro brand kit was bought from Summit Racing. A new Edelbrock Performer-Link True Rolling Timing Chain Set, Edelbrock Sure Seat Valve Springs-RPM/Torker, Single, 1.460 in. O.D., Edelbrock Performer RPM Cam and Lifter Kit. Adverised Duration 290/300, Lift .556/.581. I have a Edelbrock aluminum Intake, and a new Elelbrock 750 carb. I plan on putting roller rockers on my 8CVE heads. The studs are missing on my heads. Can I buy a complete roller rocker set-up with studs, and or bolts included? I'm not rich, by any means, but I also don't want to sacrifice quality on this motor. What is your opinion on the horsepower I will have. I am putting this motor in my 1973 Ford Mustang Mach 1. I have a c-6 transmission out of a 1983 Ford F-350 that had a 460 engine in it. (Someone told me that this c-6 should be good, because it was probably heavy duty being in a 1 ton truck). I currently have a 2:79 rear end, but I bought a 3:50 posi-trac rear end that I plan on installing. Your opinion on this issue. Should my Stang really scat down the road? It is a beautiful car, Canary yellow, true ram-air. It just needs to run as good as it looks. Thanks for your help. Your advice is valuable. John.
