Way back in 1989, I built the 440 for my 1969 Road Runner when I worked at a local machine shop. Last year, unfortunately, two lobes got wiped off the old MP .484/284 camshaft.... So, it's time to go through the engine, clean out the nasties, install new bearings and, most importantly, install a new camshaft and lifters.
The combination is as such:
1969 Plymouth Road Runner street/strip use
4-speed transmission
3.91 gear
weight with driver: 3510
1968 440 block, decked .020"
milled and template-ported 906 heads with bronze guides and hardened seats
9.55:1 compression ratio (measured) with old TRW cast pistons
forged crank (stock stroke)
Weiand Xcelerator intake
Holley 3310-1 carb
Hooker 1-7/8" headers
3" full length exhaust
I have been seriously pondering using a hydraulic roller, so as to minimize the chance of flattened lobes. Based on online research, I've narrowed my selection down to two manufacturers: Comp and Lunati. I've chosen these two simply based on track record, customer service and availability of replacement parts. I'm looking at something in the .520"-.550" lift range for use between 2000-6000 rpm.
Checking in with y'all to see what your thoughts are as to the quality and reliability of these two manufacturers. Yes, I understand there are other vendors for such items, but I really like the idea of having "off the shelf" items available if replacement parts are needed.
Also, if a hydraulic roller is used, what's your thoughts on rocker arms and pushrods? Lunati shows part numbers in their catalog, but I cannot find the parts available. Comp, however, does have stock, but YOWZA! They are stupidly expensive....
Any and all suggestions appreciated.
Thanks,
Ron
