Building a fresh 351w for my 74. It's finally happening now..
After reading way too much lately giving me brain damage I am no further in my studies, So I have come here for help.

My Bronco is a 74' with 411 gear, and 33" tire. C-4 auto.
The motor is a 74 351w at the machine shop getting 30 over and Silvolite flat top pistons, balanced,decked and rod sized..

I am not a huge climbing guy or crawler, mostly street and trails.
what I am looking for is not an all out race thing but something that sounds killer and works well at all things in general. Only driven during summer months as I live in north Idaho and it is too crazy for me to drive in the ice.

I was looking at Iron heads because of the heat issue under the hood and looking at the Dart Iron Eagle 2.02 heads. Is this a valid concern? you know, heat and all and aluminum?
not sure if I should look at the 58cc or 62cc

what are the Head recommendations here? Iron or Alum? any preferred make? AFR, Edel, ?

Cam Recommendations? 270 ish? links would be very helpful if you can :)

Thanks all and Merry Christmas!!!!

Edelbrock 5023 Cylinder Head
Amazon prime has free shipping.
we used these to replace the 76 smog heads that we used for a budget rebuild. It blew a head gasket, after taking it apart we decided to get these heads, Bigger valves than those on the stock 76 smog heads that was on there. It's a totally different animal now.
Simple swap out with new roller tip type rockers. Big improvement. Small regret of not going this route during rebuild but its all good now. some lessons cost money to learn.

cam choice should be anything a little above stock operating range. but this is based upon your usage.. 262 up to 278 should put you in the ballpark of what you want.

Call the cam manufacturers tech line and ask what is best for your application. Call several of them to ask and compare.

I put an FRPP 427W in my dad's 64 Fairlane with a tighter engine compt than the EB. We run a good 16" electric fan, 195 deg start temp and 180deg shut off temp, with a 190deg thermostat and the highest it has been is 205deg sitting in summer TN traffic. I think you'll be fine with aluminum heads in Idaho. I kinda doubt yall see 95deg days with 10000000% humidity like we do here.

Edelbrock E-Street 170cc Aluminum Heads. (Don't know the part number) Great bang for the buck. Make sure they are set up for your type of Cam. Flat Tappet? Comp Cam XE262H for Cam choice is a good one.

Edelbrock Performer Intake with Holley Sniper EFI will make a great combo, especially at altitude.
