Bigger Engine

Someone is dropping a 12 into one.


The thread is in this forum.

 

This road has been gone down many times. It would be cheaper to get a 360.

 

Seems like forced induction would be the way to get the same power without the hassle of trying to make an entirely different engine fit, not to mention the fact that the engine swap would cost several orders of magnitude more than the 7-10k USD needed to add a supercharger. Around 10psi of boost would give you the same power as a 360. You would undoubtedly have to make changes to your 3x8's drivetrain to handle the power increase. But you'd have to do the same for the larger engine anyway.

OTOH, if the goal is to have something really different, the money is not an issue, and the originality doesn't matter, what the heck!

 

I remember a shop in SoCal has put in a 355 motor in a 308 with twin turbo.
I know the 360 block will fit but it's going to require lots of mods.

Ferrari did it with a 4 liter motor, about 272 times. They got pretty good at it, called it the 288 GTO.

 

Technically, that is a smaller motor. 2.8 liters.

 

Wish they had done it enough times to make the 288 GTO affordable to folks like me!

 

I thought of it as well. Actually, I stll do...

For now I settled for supercharging reaching almost 300bhp. ( without any further alterations to the engine)

But a 430 engine would be something...
But than again, i'm lost anyway

You and me both brother.

 

Yup, hence the 288 nomenclature, 2.8 liter V8. That should be an indication to the OP of what's possible....that the addition of the turbos to the relatively identically sized 308 motor added what, 150hp to the GTO.

There's another recent post where someone wants to replace their 308 motor for more power. I'm not an advocate for this type of change, but I suppose if you follow Ferrari's lead and mount the motor longitudinally in the 308 engine bay and trunk space (boot), than maybe a 348 motor would be a viable replacement option. With the price of 348s being what they are, donor motors are out there.

You're still left with the rest of the car needing an upgrade to compensate for the additional power, especially the cooling and brakes. By the time it's all done, you're in a 355/360, except you're not.

Mark E. - a very talented engineer and mechanic who hasn't been very active on this site recently but is on that other site - had gotten I think 500hp out of his turboed 308 motor. Then he set off on a project to fit either a TR or 410/412 motor instead. Not sure if he ever finished it. IIR, he did a lot of fabrication himself. He was a top notch guy, when I first got here he taught me quite a bit.

 

It's too bad there is not a large enough market base to have data available for Ferrari mods like there is for Ford/Chevy/Mopar mods. Though, of course if there was that many Ferraris they wouldn't be particularly appealing.

With F/C/M you can pretty much look up any combination of engine/power combination and essentially get a list of the parts you need and the appropriate drive train mods to handle it. There is no experimentation to do because it's been done hundreds of thousands of times.

It's always been safe to increase power by 1/3 without worrying about drivetrain mods since any street car is built conservatively enough to handle that. But beyond that usually requires modifications. Seems like someone here said they were getting 350 or more HP (can't recall exactly) out of a forced induction 3x8 with no other mods needed. If so, that's pretty impressive, assuming they are not 'babying" it through the gears on acceleration to avoid clutch/drive train damage.

 

8.2 liter 308

328Turbo's car iir is 350hp+/-. His car is very easy to live with as I understand, based on his posts. So it's not out of the question. See here:

I certainly would enjoy more HP but I ask myself for what? These are beautiful CLASSIC cars and I have had many faster cars and love to race but the 308 is just plain beautiful and today HP is soooooooooooooo cheap. You could buy a year old ZO6 and get your rocks off cheaper than taking the torch to the Fcar and still have that beautiful machine in the garage. I'm just sayin! Lost

 

+308

My feelings exactly.

 

My feelings also.

However, if the engine was already blown up, a longitudinal install of a 331/347 all-alloy small block Ford with a ZF (essentialy Pantera) and webers would give a solid 425+/425+ hp/tq and get you to 60 in about 5.5 with a top of about 170....

That said, very few large displacement engine packages will fit longitudianlly in the 308 without the longer wheel base of the GTO such that the CVs aren't so displaced (outboard v. inboard) as to be a problem.

 

... then you wouldn't be driving a Ferrari but a Ford in a pretty coat.

A properly tuned Euro 308 does 60 in 6-ish and tops 165 mph. You don't need a Frankenstein car for that kind of performance...

But indeed, I have to say that seeing complete low mileage F360 engine/gearbox combos on Ebay for $15K, and knowing that a rebuild on the 308 is an easy $20K, makes you wonder sometimes...

 

My best friend has a Pantera, and I will say the beast is scary exciting.

 

+1 If bits are laying on the road I guess it would be logical to think about a small block.

 

Here's my plan !!! to try and fit a 360 motor on top of a 308 gearbox ??

Dave,

I would love to see how your plan turns out. Please keep us posted on your progress.

Bob

 

Hope you get done! Keep us posted. Lost

 

Carl ,the owner of blackhorse motors in LA,,,did that 355 motor conversion a few years ago,,,i actually saw it close up,,,never found out how well it turned out,,,308 s with 378 horsepower would be pretty fast i think,,,,but like the other guy said,,,it would be better to buy another Ferrari,,,,but,,not a 360,,they suck !!! lol,,,,

 

Euro 308 165 MPH,,,i doubt it...ive been at those speeds on my motorcycles,,,,no stock 308 or 328 ,Euro or not,,,will do 165....lol....
