429/460 build advise

New to the site looking for some advice on what motor would be the better choice 429/460 performance build looking up around 500-600 hp. I have a 1978 460 and a 1971 429 motor.

First the 460 has mild edelbrock part number 2167 cam / eldelbrock performer intake/ .60 over with stock pistons /with junk d3ve heads/ motors has about 1200 miles on rebuilt

Second the 429 bought this motor from a guy. It was a rebuilt he had to sell it, he did not know what parts were installed so don't know the cam size has a little bit of rough idle. Stripped down motor this past weekend looks like its .40 over all internals look good otherwise. Motor did not have original heads for a 71 so I was running semi ported d3ve heads.

Motor is for my mud truck 1977 F-250 has 2 1/2 ton rockwells 6.73/1 gear ratio/ divorced 205 transfercase/ 53 in tractor tires/ C6 auto with shift kit and racing clutches/ 2500 stall/ truck weighs around 7500-7800 lbs

have a new weiend stealth intake/ new Holly 950 carb/ roller tip adjustable rocker arms with screw in studs for the build. looking to get new cam/aluminum heads/pistons/ or any other suggestions

guess budget would be around $3500 to $4000. Thanks for any advice Bill

Never fails to impress.

From the OP's post it sure seems like a tight budget. ProComp heads and and a SFT cam type deal, barely.

I have to agree with Randy If you want alluminum heads. That's not a very realistic budget. My opinion on pro Comp heads is I would rather have ported iron they are a waste of money from what I've read. You will spend more money in refining the machine work to acceptable tolerances than it would take to buy amaerican.

I'm not an expert, but with that weight your going to need some HP. I'm not sure what your doing with the truck (just off road fun, or running in some competition class) but for your budget I would put in forged pistons, ARP rod bolts (or maybe aftermarket rods if you can afford it), get a cam designed for nitrous, MSD6A with spark retard, and spay about 150 to 200 HP NO2. I think that will use up your budget. Then go have some fun.
