Thread: thinking about building a 429/460

Tweet

Paul, I want to run the car on the street, pump gas. Power needs to be respectable, I would say 400 to 450 horse should be all I need. If we can plan the build w/more hp, but still remain reliable, and streetable, thats ok.
I am leaning more towards iron heads, because I already have a set of 69 heads, but don't know what to do with them. I've read a lot about hydraulic rollers, but cost wise, not sure its the way to go, given all the valve train upgrades.

450 HP with C9VE heads and a regular 460 crankshaft is very, very easy...even on pump gas.

• Stock block with oiling mods as outlined on our website's Technical Pages
• .030" overbore 22cc dished pistons, such as the budget TRW L2404F30
• Stock prepped rods with quality rod bolts
• OEM 460 crank
• HV oil pump
• CompCams cam kit with springs and lifters, such as XE262H (513/520, 218/224, 110*)
• Ported C9VE heads (that you say you have) with 2.19" intake.1.72 exhaust valves, requisite port work, springs retainers, locks etc.
• Quality roller rockers, such as Crane Gold Series or equivalent.
• Weiand Stealth part number 8012 aluminum intake manifold
• Holley 850 cfm List # 4781
• Headers
• Recurved Duraspark distributor or MSD breakerless
• Headers
• (this makes a 9.6:1 c/r)

The above cam may be run with oem valve train harware with a mild spring upgrace (110-120 pound seat) and oem valve train...but a roller rocker upgrade will give room to grow and accomodate bigger camshafts, be much more durable, etc. What you chose to actually run depends on other variables, and this combo is only a rough suggestion and in no way has the details.

With the above camshaft, 400 HP is about what you'd get, while a simple cam upgrade (with roller rocker valve train mandatory) can get you to 450 HP or possibly 500HP with other bolt ons.
