bence13_33

I'm not really sure but here are some prices from Jeg's:

427 - 505HP/520TQ 10:1 Compression - - $8494.99
427 - 530HP/540TQ 10:1 Compression - - $8994.99
427 - 625HP/570TQ 13.9:1 Compression - - $10,494.99

Those motors are complete from carb to pan. Here are there prices for shortblocks:

427 - 20cc Dome Pistons - - $4594.99
427 - 10cc Dome Pistons - - $4594.99

There's a good starting point, maybe others will chime in with some various other prices.

Had been eyeballing their 434 short block for $3695 but looked unde the 'What's New' section and saw this add:

Don't know the first thing about the place but it is with in driving distance for me. :steering:

Check out http://www.lbwengines.com they have good prices and use quality parts in their performance engines.
I had already bought my 427 ci Bill Mitchell then I found LBW site. Had I known prior to buying the Bill Mitchell 427 ci .....I would be able to tell you more about the Hurricane 427 ci from LBW. Good luck in your search.
These big number ci small block engines are very nasty critters in the quarter and on the road.... :thumbs:

This seems to be pretty decend engine:

How about a Merlin? Less$$$$- more HP/ LOTS more torque.

my opinion

A big block looks like a big block and has no less that 396 ci. A 427 small block can easily mascarade as a 350...if that sort of thing is important to you.

And, depending upon how it's done, a big inch small block can be built for a lot less than a similarly performing big block. Weight is also an issue. The key to these heavy breathers is in the cylinder heads. Sure, you can make the torque easier in a big block due to the big heads but with what's available in the aftermarket for smallblock heads, it's pretty easy to support the air flow.

MassVette

No way. Substantially more $$$$$ for the big small block.

80#?

Likewise for the big block............

It really boils down to stubbornness, I think. The small block is a fabulous motor for up to 400 hp or so- after that- the the 'law of diminishing returns' kicks in, IMHO.

Well one of the reasons I built a 434 small block is that the cost difference between building a 406 and the 434 was the cost of dished pistons. Everything else was the same price.

A 4" throw crank doesn't cost anymore than a3.75" throw...

72 Stingray

That would be me...

There were some guys over on the Team Chevelle forum talking up Ohiocrank pretty well. They had used several of their race motors out of the box with very good results. I haven't bought from them, but I may if I decide to build my own and not go crate.

Since I'm just down the road from Fevre, they are within driving distance for me too which is a big plus.

Cappy did you get your 427 dialed in yet? How about the roll bars?

I need to get serious about completing my 427 Motown. I need to buy a few more parts. I'm going to be running Crane Pro solid rollers on the Comp Cams H-roller cam.

This DD2000 sheet looks pretty good for a 7000 rpm red line - Click on the picture to super size it!

454 tq at 2000 RPM, that's sweet :cheers:

Tominator and you others. 427+ ci motors require lots of air. So be careful when sellecting heads and cams. I have a set of AFR 210 new in the box just from AFR. Simulations show that these heads using the CFM flow files are down 40 hp and @ 20 foot pounds. So the more logical choice for these big motors are heads in the 220+ cc class like, AFR 227cc, Dart Pro 1 227cc, Brodix -10 or -11's or simular heads flowing in excess of 300 cfm at .600 lift

You can't really run any hotter of a cam because you start getting your max power to close to red line. So you have to run the biggest heads you can budget for. The only way I could exceed 600 hp is with the next level of heads with monster valves and 18 degree stuff. My max power is 1000 rpm from 7000 red line. If I would have kept H-rollers max power would have been very close to valve float.

Rick, GO BIG BLOCK!!!!!!! Especially if you are looking to buy a complete engine and not rebuild yours. A small block at 427 ci is close to being "maxed out" (434 ci). Where if you went to a big block, let's say a low 500 ci engine, and in 2-3 years you out grow (get bored) with that you can outfit the engine with a new rotating assembly, maybe a 600 something ci. Also nothing LOOKS better than a big block "shoehorned" into a Vette. One other thing..... you will then be able to beat me.. :D

I know this isn't the FS section, but I have a 420" shortblock new never run with all the best parts I could afford I would like to sell. 4-bolt block .020 over, H-beam rods, JE pistons, big solid roller cam, road-race pan, etc.

I am building a 592, so I don't have a place for it but I would sell the 420 for about $2,700.

GO BIG BLOCK!!!!! GO BIG BLOCK!!!!!! :D

gkull

lotahp - Cappy and I were laughing when someone said the answer is "BIG BLOCK"

NO! the answer is big small block with a blower. The tall aftermarket blocks are good for just under 450 ci IMO. I think that the cylinder walls are just to thin with 454 ci. The 440 ci varieties of small blocks are starting to be built more often.

I can not concieve all of the problems from changing over to a big block.

LOTAHP

gkull, for road racing or autocrossing small block is deffinitly the way to go. But for drag racing..... torque is what gets you down the track and no matter what small block you come up with it will not compare to the torque of a healthy big block. And if Rick does not plan on racing his car, "showing off" a big block out does a small block any day. I do not see any problems converting over to a big block. He's got a 5-speed manuel trans. If he starts "beating" on it he might have to beefen up some rearend components.

As long as the blower comes to the roof line

Small block, Big block sooo many choices I'm confused. What bothers me most is I like the idea of creating my own monster but don't want to make a mistake.If I buy a complete motor then I won't have the satisfaction of knowing that I built this myself and I may have paid too much for something.
So I will do more research.

Question for you guy's will a stock 400 block hold up to 550hp for street use????
