what v8 would you choose?

[bkfirebird]

This winter I'm swaping a v8 into my Firebird which right now has a extremely slow 3.1, I mean my smoking 350 truck with 210,000 miles on it is faster then this thing

anyway, my dad is a mannic and in his days has had some nice cars, his latest which he got rid of a few years back was a 66 gto that ran 5.5 in 1/8 and now hes building a 502 with 900hp that hes putting in a 69 camaro or firebird.........anyway

my dad and I have thought things out and have come to the conclustion that I want to get a 400small block and build it up with dual carbs. I'd like to know what you all think about that and opinions, such as if I bore and stroke would it be 427.....or should I do a built 305 or 350 vs the 400.........I mean really they are pretty much the same but I see more poltenional with the 400 because it has 1.1litres over the 350......anyway drop your opinions!

Is this going to be a daily driver or a weekend strip car?
Either way if you drop a big engine then it's not just the engine that's going to be changed. You are talking major money pit. You'll change out the tranny, rear end, suspension, etc. Your best bet would be to find a 350 TPI engine and get it worked on. This way you'll have a good strong engine you can drive everyday and still be able to work on it. You'll still have to swap the tranny if you don't have a 4L60(can't remember), and also get bigger wheels too.

well first off all for some reason my car came with a Formula Suspention Package and a 700R4 tranny.....how I know? my dad ran all the numbers.....oh and of course bigger tires along with 3.73 posi, I got all that shit set......and this car isn't a daily driver, it's intended souling for a plasure/crusing/weekend car

Thanks for all the advice

[Ozzy88GTA]

That's cool, sounds like you got a good working partner. You still might have to get the tranny beefed up some since the 700R-4 has it's limitation on the power it can handle. A 400 ci small block sounds like a winner to me. Good torque and HP yet not too much of a gas guzzler even for weekend drives. Good luck.

Change the whole rear end, the stock ones are very weak.

I would go witha 350, because they are relatively cheap but still have great power potential.

[petereggy]

a 400 would be better then a 350 just for torque

but if your looking for all out power torque sound and fun try finding a 455 and doing some work to it

[FAPhoenix]

I have a link with all the information on dropping a 455 in it. Now that would be a different car thats for sure

There is a 3rd gen in my town running a 455. One quick car. Plus its a true Pontiac.

I think the 350 is the best. It should be able to rev higher and will still have good torque. I read I think a while back that the 400 block and heads have bad water passages compare to 327/350 block. I could be wrong though. The 400 sbc was never intended to be a performance motor as they never even put a 4bbl on it from the factory. But then again many 400's have gone fast on the tracks. I think 350 is the best all around choice then 400 and not the 305 unless it was a low buck daily driver.

[petereggy]

Hey smart guy Im talking about the SBC 400 it was always a 2bbl used on chevelles/nova/wagons and I think trucks. Yes the I heard of the pontiac 400 and I know they have rochester 4bbls.

[petereggy]

ok so why are you talking about a chevy when everyone else is talkin about pontiacs?

[DeViL]

If it ain't going to be a daily driver I got an engine for you.

It's a 350 V8 called the ZZ4.
Here is a list of what it includes.
