273 or NOT 273?

-
I priced a 4 barrel intake for the /6 and it's cheaper to get one for a V/8. I don't know how much pistons would be. Dollar for Dollar the 318 would be the best way to go

Why 318 not 360 or 440?

You have gone on and on about wanting to do a 318 over a 340/360 but that's ok but a 273 is just one step to much over the line lol. The OP thinking about doing a 273 makes more sense then your obsession with a super torquey low rpm 318.

340 ft lbs from the factory with 2bbl..... I've always doubted that number a little

Base is stock 2bbl 318 with headers, doesn't even make 300 lbs-ft with headers.

Mod 1 is 4bbl and xe262h
Mod 2 is a spacer added and finally makes 340 lbs-ft.

I don't think so. He would be money ahead doing the 318. 318 has a better bore to stroke ratio.

Talking to my builder this afternoon. He will let me know if I'm wasting my time or going to be that unique guy showing up at the cruise night. (with empty pockets)

i'd be way more impressed with a small block of any size that's got an old school paxton set up (a la 67 shelby) and some trick circle track hardware like a dry sump, remote power steering sump with a cog driven pump and custom bracketry that's not all bling and billet along with some really nice custom headers.

and it wouldn't even have to make beaucoup power either. just the visual alone and if the work was well executed would get my nod over a whole bucket full of other stuff.

Here we go again, why stop at a 318, he would be money ahead going to a 440 and have a REAL **** eating grin on his face when he lets down the hammer.
and probably have to cleanout his drawers if he's used to a 273 or 340. lol

The 360 would be a good choice. I mentioned the 318 because some compared the 273 4 barrel to the 318 2 barrel which is a unfair comparison because the 273 4 barrel has more cr and more cam. The 273 is limited by its small bore size of 3.625" compared to the 318's 3.910" which is a .285" difference. If the 318 were to have the same cr and cam as the 273 that would've been a better comparison. That's why I mentioned the 318. The 440 would be good, but there's the extra weight. I think that a 408 would be a better choice over the 440.

Obviously you haven't read the thread, he's already got a 11's 340, he's thinking about playing with a 273 and want's to know what it will take to build a low 12's 273.

You've never driven anything with a 440 in it imagine it with a 4.00 or 4.15" stroke. lol
I still think a 273 build would be a fun challenge if that's what the OP want's to do.
otherwise why set your sites so low when it comes to the wallet, I can build a 512 for the same cost as a 408.

Why stop there. How about a 500 cube blown Hemi out of a top fuel car? Some people do that just because they can.

My dad had a truck with a 440 and it ran pretty good. If the OP wants to do a 273 for the challenge I say go for it.

No, I haven't read the entire post. I only spoke up when someone compared the 273 4 barrel to the 318 2 barrel, sure the 273 will rev faster because of more cr and cam. I think that dollar for dollar the 318 would be better but that's upto the op
