My possible 466" project

I finally have enough room in my garage to rebuild my engine. It's coming from a 1978 F-250, as the title says, I'm going to clean it, strip it down then off to boring and honing. I'm going to get a eagle racing assembly, edelbrock RPM heads(95cc), along with RPM air gap manifold, a 750cfm carb, and some headers. I also wanted to get a custom flat tappet cam, just to make sure I'm getting the valve action I want and keep the cost a little lower. Right now I don't know which carb I want, leaning towards even more edelbrock. I don't know what kinds of cam specs I should want. The headers that are available are kind of slim. I know there are hedman, mad dog, flowtech and hooker.

I'm running a C6 and swapping in a ford 9" for the rearend. It's going to be mostly a street hot rod and in the future maybe a little drag.

What kind of cam specs should I be running? What companies are reputable in carbs? Headers? Fuel pumps? Water pumps?

Thanks for the help everyone! Once I get the engine ready to come out I'll start posting pics.

What is your power goal? The complete Performer RPM top-end kit is good for 509hp on a 9.5:1 shortblock. Seems like a decent start. A bigger carb and a little better cam could probably get 550 on the same short block.

PS I have never seen it listed in a catalog but Edelbrock does have a part number for the complete kit just call them.

How much bigger?

Application?

Mostly cruising, street prowling for ricers and some commuting (Probably less than 15 miles a week).

I knew when I got myself my truck I wouldn't really see anything 7mpg, but 466 vs lets say 502. How much more would it suck up? How much more horsepower would I be looking at if I used the ford heads instead along with stroking out to 502?

I'm not looking for a mileage build but I want to know what kind of gas money I'm going to be asking from my friends. It does have to end up being pump gas friendly.

It's about 4,600lbs and with RWD. I think around 30" tires, I'm probably going to end up getting a custom rearend so I can put whatever gear ratio I want in there.

545" does sound tempting...

Well, to be honest don't really know, at the very least past 500 hp. I think from lurking so long on here, I've wanted to go bigger and bigger for my engine. It's gone from 466-502-521 back down to 502-466 now 545 sounds almost irresistible.

What are some good companies to buy from for stroker kits? I'm pretty new so I've only heard about Eagle and Scat.

While your gathering parts, ever think of trading that C6 for a C4? A Powerglide would help with street racing, IMO. Watch out for the "ricers". Those with turbos, chips and all wheel drive can embarrass a guy at times!

Dave.

Yeah, I'm going to stick with my C6. I'm aware that if the ricers have four wheel drive, and a turbo they can embarass me. You can usually hear the turbo whistle on anything remotely serious, so going try and do my best at picking my "victims."

I'm not planning on towing and if anything I'll be taking trash to the dump. I'm really considering 4.3/4.5 stroke with my 30 over-bore. I'm guessing my mpg won't be much worse due to the fact that my engine currently burns quite a bit of oil and unburned gas is probably going out the tailpipe. So what kind of HP and TQ would I get out of the 545 with scj heads, 850cfm carb, rpm air gap, flap tappet cam with those specs, and some 2" tri-y headers? Would I need more carb?

I'm going to dyno and get it professionally tuned before I put it in the truck. Any good readings to polish my ford performance building knowledge? Just check my measurements and torque the bolts right, then check again and again. Just like a whole short block rebuild but with more metal right? Oh, and what would be a conservative RPM redline for this engine?

Personally none my dad has done a one or two. Would it still be do-able?

I have considered it but I just don't have enough money for the quality of parts I want+labor. I need this build to be reliable and I'm confident enough in my ability that I can do this. I'm going to read up while I'm taking the block out then make a final decision on my build. I think Bill would be a go to for the machining though. Would a stealth manifold gives this build a little more torque that I could actually use on the street? Thanks for letting me pick your brain apart! Hahaha
