View Full Version : Cubes for the street?

Could have been a poll and will be extremely subjective, but curious in the opinions out there in what some of us consider a 'reasonable' cube displacement for the street....402? 416? 427? 440+?

I know its all relative and lots of factors play a role; cam's, gears, intended use, etc. We can sort that out. I guess what I'm interested in is a discussion in how many of us have caved in to the "mine is bigger than yours" paradigm given the 'pressure' (?) of a constantly evolving aftermarket industry and have sacrificed some function for form.

I myself am heading down the road of 'go big or stay home' with my winter project, so I'm interested in the community opinion :D

This will be fun...

N/A.........there is absolutely no reason not to go as big as possible that the budget will allow. Bigger engines make more power and are more streetable and idle smoother than smaller "built" engines. So its all about the $$$ you have to spend.

What he said.... my 461 is more streetable than many 402s or 427s I've seen..

When going NA go as big as possible.. the cubes can suck up big cams and make them very tame compared to the same cam in a smaller engine.

Glad to hear you say that seeing how you're recent build will have me by a cube! Your horsepower number were encouraging too...my combo will be somewhat different; stroke, bore, PI LS7 heads and a little more 'snot' in the cam, etc. A lot of the specifics are still be sorted with the builder, but we'll get there over the next couple months. I'm also looking forward to hearing your update once you've run that beast on the street.

For the rest, I am going N/A...and spending 'enough' (wife is thrilled, lol :barf: ). Originally looked at a 440 but looked at what it took to go 460 and figured..."well, I'm already dirty" and decided to go for it. Should be kicking off the process next week. Glad to hear everyone's thoughts mirrored my own...really looking forward to this project.

The only things that a big cube motor limits you to are gas in the tank and traction at the tires.

Plus all the weight you save by having a light wallet!

+1 for bigger is better.

^^^ That's what she said. ;)

I too say Go as big as possible. Sounds like the plan is set in stone! That 460 should Really scream. (I'm Subscribing myself! And can't wait to see the end product!)
Good Luck with the build. And if the girl starts to complain too much, trade her in for a dog. :D
j/k

Considering what you paid a few years ago for a set of ls6 heads and a sleeved ls1 block that was hit or miss for reliability I think the prices have really come down.

hahahaha!! That's great!
I have 4 dogs. (3 Pit Bulls and a Shepard/Collie Mix) :)
And I was in a similar situation with my Fiance' with my last build. She kept asking me HOW MUCH is this gonna cost? I was like uhhh about $4k, needless to say that price More Than Tripled by the time I got half way done. lol
Oh well, You only live once. :D
I Can't wait to see her face with the new build this winter. :jest:

Good luck with your new setup!

Thanks James...WE are looking forward to it!

Made the project semi-official last week; not official imo until its sittin' between the fenders! Made my first installment kicking this thing off...there will be more 'installments', lol.

Foundation will be a RHS block in a 460 configuration....Virginia Speed doing the build. Should be pretty cool...and enough cubes for the street :cool:

Congrats!
I'm sure you BOTH will be very happy with it. ;)

Can't wait for the end product! Make a build thread... :D

For those who like big NA engines, check this one out:

Might be a tough fit but you got to admit it is kind of cool to get over 2K hp with no power adders.
