I have a 318 (5.2L) Magnum V8 in my truck with 160,000 on it.

>>17130487
Stroker kit from hughesengines.

>>17130541
True, but start with a 360, bigger bore.

>>17130487
Just get a supercharger. Pretty much a bolt on enhancement.

>>17130541
I was definitely going to stroke whatever I did, but is it not worth it to find a 360 junk yard engine and stroke that? Does the 318 deserve to be stroked?

>>17130591
Hence my question

>>17130618
>my only reservation is that I want to stay away from boost

It's a van so there's literally no more vertical room for a supercharger to sit on anyways

>>17130634
oops. didn't read that far ahead. Don't be a pussy and get the boost. Get a big ol' blower and stick it out of the hood.

A blower would stick up through the dashboard and windshield. Plz

>>17130487
no
no
no

invest in a platform worth building 400hp and try again.

>>17130665
Stroker, small turbo, and/or LS swap are your best options. I'd probably just go with a junkyard LS because they're already within spitting distance of 400hp. With a little bit of TLC (and the right parts) the LS will easily make more than 400hp.

>>17130688
Suggestions for something that would fit, and is worth building in your opinion?

>>17130690
I was considering a 4.8 turbo sloppy mechanics style, but I don't know if I'll have the room for all the pluming since it's a snub nose

>>17130693
nothing, its a fucking van.

go buy a c5 corvette if you want 400hp.

>>17130703
The small blocks are really quite compact. Smaller than a V6 in some instances. If it can fit in a miata surely it can fit in your van's doghouse.

>>17130719
Well yes I know the ls is very compact I'm not worried about that fitting at all, I was worried about having room for the hot side and intercooler and so forth.

>>17130728
but you wouldn't have an intercooler if you did a NA LS. anyway just get a hoodscoop and put an intercooler on top a la subaru style

>>17130778
Is 400 whp really that attainable with an NA junkard ls?

>>17130778
>intercooler on top
what are the benefits?

>>17130842
not having to put in front of the radiator.
>>17130828
pretty much, yeah.
A wuick google search (400hp junkyard LS) yielded this

Remember that a good tune will go a very long way.

>>17130828
Bolt-ons and a cam should net you 450 WHP with a good tune.

>>17130900
Huh good to know. I know the 4.8 and 5.3 are favored for boost but if I was going na would a 6.0 be the best choice?

>>17130913
It probably doesn't matter that much because you're looking at iron block motors anyways. If you really want to be safe, look at the compression ratio each one. Low compression is generally why an engine is favored for boost; less likely to blow the fuck up.
I'd still stay away from the 4.8, it's the displacelet LS.

What's the benefit?

You want to have the intercooler supplied with a steady flow of cool air as cool air can be denser. Therefore you want it before the radiator heats up the air. Having the intercooler supplied with only hot air would almost negate the effects of having forced induction.

>>17130487
360 swap, keep it mopar
of go even bigger and throw a 383 in it

>>17131092
>>17131118
woops nevermind. I read your post wrong. The benefit would be to save grill realestate and minimize piping length.

>>17131072
I think you misunderstood my question. I'm NOT looking to use boost. I said the 4.8 is popular because it takes boost well, but since I'm going NA is the 6.0 my best bet for iron blocks?

>>17131136
I'm not necessarily worried about keeping it in the family, unless a 360 is pretty easy to get 400 out of. I know swapping a 360 would be a lot easier than an LS.

The trans blows up even with stock power. Good luck with that

>>17130487
I fucking love my 360

Sell it and buy the same truck with a Cummins

>>17132252
I'm obviously getting an aftermarket tranny

>>17132591
Built?

>>17132866
The van was not sold with a cummins

>>17132957
>truck
>van
Make up your mind, is it a van, or is it a truck?

I don't think I ever used the work truck, but it's not like it would be wrong if I did
