Contemplating a turbo in my future possibly for my 451 BBM. Would the easiest method be to install a typical HP exhaust manifold upside down on the driver side/installing the turbo from here?

I am no expert on turbos, can someone kind of school me on everything needed in a budget 76mm turbo build I may be overlooking.

Looking at around 8.5-9:1 Compression.

5-8psi boost. Do I need an intercooler at this level?

I would switch to a Mopar 528 solid camshaft, as I could make up a majority of the power loss with the turbo. My camshaft is currently 272* dur @ .050, with a 106LSA (.590 solid). Head flow is 290/220 @ .600. 10.5:1CR. Victor Single Plane. Transmission is a 833 4-speed, DFX clutch. 4.10 Gear currently, would switch to 3.23. 30x12.5" ET STREETs on rear currently.

Main Parts:
This chinese turbo has nothing but good reviews on the turbo forums.. and is dirt cheap! Probably would use something like this (Ebay) ($265) (GT45 76MM)

Turbonetics (Craigslist) Wastegate ($180):

Aeromotive or Holley HP 150 fuel pump

MP 528 solid camshaft (241* dur @ .050/112LSA) ($200 new).

Custom head gaskets to lower compression ($150?)

TiAL BOV (Ebay) ($225)

Mechanical fuel pump BOP ($15)

Aeromotive Boost Referenced regulator.

MSD Boost timing retard box (ebay-used)($150)

C-Body exhaust manifolds ($150 shipped)

Front mount intercooler (Ebay, used/new) ($150):

Cant see it costing more than this to modify my carb ($400).

Basic Tuning ($400) (Maybe could eliminate this cost by tuning with a friend that has a 800rwhp turbo fox/700rwhp procharged fox as well)

Odds-Ends-Fittings ($400?) (little things that just add up)

Turbo piping fabrication ($500-600?) (This could be hardly anything if all I need to do is fab a downpipe through the fenderwell)

Around $3000-$3200 total..

I would suggest looking at a dual turbo setup.
EFI conversion would also be preferable to a blowthrough carb setup.

they put turbos on 440s and 360s in motorhomes in the late 70s draw-thru setups but the rare and hard to find

i bought a uhaul style box truck with a propane powered 440 in it and it came with a draw through turbo system they through in the back., I sold that kit for more than i paid for the whole truck

To start, is this a full tube chassis off road race car? If your building a 8 second chassis car I suppose a BB is in order. If not you may want to make more room and build a 318. Twins are also not a good plan, your steering and brakes are on the drivers side and get melted. The small blocks also make running a real distributor a lot easier, 88-92 TBI. Then just need a self tuning 4 barrel TBI. Get one with 85lb injectors and crank up the fuel pressure to at least 55 PSI. Hook up the 2 or 3 bar map and drive it to tune it.

Just using a few 2.2 tricks can get you to 1000 WHP with a 318. You see them running around with 750 WHP and a carb. So done right with FI a 318 is the best street choice. Extra room and less weight is also nice.
