Mild Turbo Build

Hello all from Warner Robins, GA
First post, but have been a member for a few months. Looking for advice on a "junkyard" turbo build. Here's the details...
1. Intended use will be primarily street, will probably never see the track. Just stoplights and wow factor.
2. Vehicle is a 1972 F100 short wheelbase; crown vic front suspension; Explorer 8.8 rear w/ 3.73 track-lok 31 spline axles flipped w/ leafs, planning on triangulated 4-link w/coilovers.
Transmission is stock for now C6.
3. Fuel desired is pump gas 93 octane.
4. Budget for turbo engine build is approx $5k with more as needed.
5. Engine is 460 from 1979 f150 (dad's)

Plan so far is stock crank, maybe forged rods if necessary, and forged dish pistons. Refresh the stock heads with a turbo cam installed. Single plane intake & 850 cfm blow thru carb. Looking for approx 700whp. Heart is set on building a twin turbo engine. Will need pointers on fuel system setup as well.

Any suggestions are greatly appreciated.

Well, I guess no one had any input. Does anyone have a line on a BBF knowledgeable machine shop in the middle Georgia area?

Wow , impatient much lol . Sounds like a good recipe. Will be a nice tough streeter , get some drag radials on there
That stock C6 will need some work for 700 RWHP.

Looking to do similar here with a friends setup. We were looking at big single turbo, unsure on sizing as yet

Jon Kaase's shop is in the middle of Georgia. It pretty much doesn't get any better than that.

A twin turbo 460 build for only $5000 is a very tall order unless you use all parts from the junkyard. But that begs the question how long will it last.

You don't need an 850cfm carb to hit your goal, save the money. Re-gap the rings toss on a pair of GT45's and let it eat. What's the worst that happens? You blow up a $200 stock 460? You won't have to spin it high enough to worry about the rods to make 700hp with twins. There's single turbo bone stock 460's running around making 500 to the tires without ever even having the heads off the engine.

this is true, there is a local guy here that runs a factory 460 from a 75 lincoln in his f100. its twin turbo making 10 pounds of boost, he's had a built long block sitting in his garage for over 2 years now waiting for this one to pop. he doesn't spin it over 5500 rpm and he's got it really well tuned so that might be a good reason why it still runs. the only upgrade to the motor was a new timing set and a set of 3/8 pushrods other than that its a 40+ year old factory motor. not sure what his truck puts to the ground but it f*ckin moves

Thanks for the replies. So is the general consensus to ruin a pair of GT45s? Also, does anyone have an opinion on the FITECH or Holley sniper self learning systems? Gotta get a new carb so I figure I might as well go that route...less tuning.

Cool

Given the iron heads will be un ported and are D3 in style I would use no LESS than 20 additional degrees of exhaust duration after you've settled on your intake duration and operating range. I'm sure you know about wide LSA etc...

Back cut both the intake and exhaust valves.
Spring the intake side to deal with the boost behind the intake valve.

Thanks for pointing out another aspect of the build that deserves careful consideration. Any recommendations for an off-the-shelf cam grind? The word custom scares me price wise...single income family.

Just read that Comp does custom cams at no additional charge. I'm sure everyone knew this except me. Lol
