Turbo kit will make more power than a N/A 347.Turbo kits a easy now a days.Call a company like Hellion and order a kit,bolt it on and viola.

THAT really depends on 1 or 2 turbos and how much boost vs how wild the 347 is, I've seen many a 347's put some turbo rides to shame

I'm sure he doesn't want to have to fill up every 1/4 mile.

No Replacement For Displacement.


And thats a difficult question to ask saying how much work is involved.

Easy answer for the 347 is alot of work.

Starting with replacing the bottom end, it would be much easier with the engine out, which takes a long time.

You then realise that the block needs to be boiled and probably decked, maybe punched out but at least honed.

Then you realise your oil pan, oil pump and what ever else you broke durring removal all needs to be replaced = $

The kits fairly cheap, put that in should be fairly basic with the proper tools and torque charts.

From what i have heard from everyone on this thread is your gonig to need some bad ass heads to feed the need.

The trubos a much better bet imo for simplicity

But personally id rather rebuild a solid bottom en,d and know it will last me a long time.

But the same thing applies: say you go 347 you can always boost it later/

say you buy the turbo, im pretty sure if you decide to go 347 im pretty sure you can still use it? maybe? noon on the topic here not sure

also question will a 347 be alot harder on gas then a 302?

i personally would do the 347 and i am starting to now,

( had a guy with 3 stock 302s for sale and i emailed him about them but he threw them all out cause they were in the way one was a 90' with only 100k miles on it tear ) anyway

id like to say i touched every piece in the engine and i know everything about it
its gunna be expensive, but the $ never stops with the 5.0
it will be much more time consuming and probably more $ but its all in the fun of it!

If you are going to build a 347 and boost it,it will never live in a stock block, in the real world a one piece rear main block always breaks around 600 hp at the wheel.I don't care who you are or who you know,the block can not handle the torsional loads at the hp level.You could put the turbo on your engine now make some good power and in the mean time, before you break it, you can start on the next one making it handle a 1000 hp and turn it down to make safe 800.I also don't care for the 347 in that deck height.Go 331 ci in an 8.2 unless you use big bore or use a 9.2 or 9.5 deck, it all cost the same when your at that level.

with the 347 your going to need the crank, rods, pistons, rings, bearings, gaskets, machine work. on top of that your going to need good heads, push rods, bunch of new gaskets, new head bolts/studs, and exhaust upgrades would be good. youll see 350-375rwhp on pump gas

with the turbo, you just need the kit and fuel upgrades. the kit will of course come with headers and dp so no need for exhaust upgrades. youll see 400-500rwhp depending on boost level on pump gas

depends on what you want tho
