Thread: Big Block displacement outta small block

Tweet

What do you guys think of the super displacement small blocks? World Products has several. A 454 is their latest and biggest but they also have a 427 and a 415. They use custom blocks though. Anyway I'm looking to toss the 305 in my 3rd gen T/A next year and am wondering what my options are. I thought I'd stick with a small block, the venerable 350. I was wondering what a big block would require as far as suspension ect. I'll probably be going for bigger brakes already but i hadn't wanted to mess with the suspension too much and then there is mounts and I'm sure a ton of other stuff. Anyway, I then came across an article in Super Chevy about this WP Motown 454. It weighs about 450 pds pretty complete with aluminum heads. It's quite pricy at $10,495 but it is almost compete and making 610 hp at 6,400 rpm and 584 lb-ft at 4,500. Something like this (or ore likely the smaller one) shouldn't involve suspension mods and it says all chevy small black stuff bolts on. The drive train is another story but I planned on going with a different trans and rear. I guess my options are 1)nicely done 350 (possibly huffed) 2) a big block 3) one of these 4XX small blocks. Any opinions? Everybody's got one. Thanks. ---Rich

A big block would sling that t/a.......my 454 is a stock block (slightly) modified in my 78 f body my suspensioin has stayed the same except for some bigger springs and a bigger swaybar and does just fine............the only subsitute for cubic inches is cubic feet.......

Get a 403 Oldsmobile block. Very reliable, comparitivly cheap and they are in the yards. Dont use NOS or a blower and you're in good shape.

I personally love these large dispacement smallblock chevy's. They are awesome ,if you have the money they are well worth it. Take a aluminum head , cast iron block smallblock chevy for the street and you have great combination. Light-weight and so many perfomance part's to put on them.It would be my choice hand's dowm.That's only my opinion though you will have to decide fo yourself. Good luck either way you decide.
