looking for new engine ideas. So..., what are the chances/ costs of finding a 427 engine??? Just curious if I should really look or not

Find a good 454 block and get a $250 427" crank here...

www.competitionproducts.com (http://www.competitionproducts.com)

page 67 p/n #427 and they have 'blems for $150. Don't really know what 'blems' means here.

Don't wimp out, build a solid 6500+ motor, they don't mind it at all.

How's that? I'd say your chances are 100% certainty. ;)

If you want an original vintage 427 get out your checkbook. They can be hard to find and even junkers are going for premium prices.

The best route is a 454 block with a 427 crank as mentioned above. Pistons can be a bit of challenge if you want something more strong than a hyperutectic but they are out there. JE/SRP makes a nice slug that produces roughly 10:1 with open chamber heads.

Then, get ready for all the arguements from everyone. Yes, you can build a 454 or a stroked & bored 454-derivitive that will produce tons of low end torque that you'll never be able to get to the ground on the street anyway. smile.gif (If your goal is for racing, go with the big cubes for more power and reliability though.)

Besides, there is just some incredible mystique to "427" that can't be matched by any other numbers.

Once you go 427 RAT you never go back!!

Have 2 in my stable both original 512 casting 69 blocks, would never run anything else, cranks up to 7400 in a blink of an eye.

If you do build one i would recomend trying to find an old Ultradyne cam for it, remember "Don't scrimp on the gravy" graemlins/thumbsup.gif

Look, I'm not a braggard, contrary to my nature.

However, my old 427L88 I built as a kid came back to me from a friend a few years back. He went 510".

Well we lined up last year, while he beat me, the first run he didnt think so ( 11.85 v 12.24). Old Red out -mph'd him every run. To wit, that little 427 is making MORE POWER than his Dart headed 510". Might be the 67 is lighter than his caged 68 Camaro, but we don't think so. And I had 35- 40 lbs on him. We guessed Old red at +300 over his BEAUTIFUL 68. ( I think he needs a bunch more cam ).

Of course, I threw decent gear at it ( 4.30s), compression (10.5), and a nice 'little' UD cam, now the Lunati 402A3, which is IMHO, A PERFECT 427 cam.

And BTW, not to start any kind of debate here, but I built an old school HP motor that swings to 7000, not the more modern low end grunt motors everyone is so fond of. Only because it was a retro-style resto. My point, I don't think I'd build a 427 for "torque" per se. Build it to make max HP at 6400-6800 ( or higher if you have the $$), gear it accordingly, and start hunting for 502s. Stock 502s are good competition for a geared 427.

Added benefit if you have some sort of OD tranny,is that 427s are a bit kinder on gas milage. Nice motor, Don't think I'll ever build a 454. Short stroke/high rpm rat or long stroke/big bore 4.6" rat. Nothing wrong with a 454 BTW, so don't mistake what I'm saying here. But if I use my old L88 4 bolt block, I'm sure I'd stroke it for a mild low end motor. ( unless a free 4" crank falls in my lap).

When I had the 4 speed in my ride the old hydraulic cammed 10.37:1 460 went 11.88@120.46 with less gear at 3,800lbs+ race weight never turning over 6,200RPMs. But I agree, 427's are a nostalgic engine smile.gif

Yeah Ken, I want to be carefuly, I don't want anyone to walk away saying, " Chaas said 427s are better than 454s" no , not at all. Different is all, yet I would encoruage folks building stout 427 to let them breathe and run to 7000 rpm.

Same piston speed as a 454 at , what 6600 roughly?

Ken, I havent tried to 'split my case' yet, and likely won't until after we move and the $$ reserves are built back up. With a 1.80 60' the car should run 11.80s as well. Shifting at 6700 though.

I know Gene, I'm just having fun with you. If you can get 11's on a 1.80 60' then that's great! Here's what my time slip looked like on the pass I mentioned earlier:

60' - 1.76
330' - 5.059
660' - 7.731
MPH - 91.96
1,000' - 10.002
1,320' - 11.889
MPH - 120.43 (I thought it was 120.46, failing memory)

No doubts on the 427ci engines here. Recall my old man clicked of a 10.99 pass on his L72 M22 4:88 geared SS/D Bolero Red 67' Chevelle (yeah, he was cheating) way back in 67' He had a custom ground crane cam, Holley 1050 3 barrel carb, flame thrower ignition and custom head work by Bo Laws out of FL. I know those things will run :D

So back to my original question, is your buddy's Camaro a stick or auto? I'm guessing an auto.

Reading right along..

I love high rpm short stroke motors like my old junk 301 but I ALSO like the grunt my 406 had!!

It's a toss up, that's why I think a 4.625" bore x 4.375" s = 588" BB motor would be the best of both worlds.

So many cubes that grunt would come naturally, but still big bore and short stroke enough, it would run much like a solid cammed, 327!!!!!!

And I bet one with a 396" crank in it to make a 505" motor would run like the little Z-28 motor, too!!!

Yes, too many good running Chevy motor sizes AND just not enough money to build them all... He, He!!

Please continue..

Ken, sorry yes auto. And he's having issues with it, 2nd gear issues. Mild 2800 stall is all. ( he tried an ST10 and blew that up - however IMHO you start using those steel-based clutches and you end up shocking the case/gears too much. Don't know. Softer CF clutch **might** allow the box to live longer.)

Where did your dad shift?

PDq, yes, exactly, " different strokes for different folks." ;)

the SHORT version of my above diatribe is simply; let a 427 rpm to make excellent power. Shoot for torque peaks in the 4700-5300 range and let 'er spin to 2K above that. If'n you want a stout 427.

Pop's says he used to side step the clutch at 6 grand and shift at 6,800. He says his trap speed was 130 MPH. I think that may be true as they used to report trap MPH rather than an average of the last 66' (I think is how it's done today). He said the guy that spec'd the cam for him told him that he might run out of RPM before the stripe with that deep gear. Dad said it was real close. The index in SS/D back then was 11.70. With his "special" combo he could run under it at will. He said the SS/A hemi's still had to spot him a couple car lengths though smile.gif He ran M&H slicks and tall Stall front tires. I was talking to one of my aunts a few weeks back. She seems certain that she has some Super 8 (?) footage of my dad racing at Yellow River in 67'. I asked her to see if she could find it. Everyone that knew my dad back then said no one was faster on the gears. That's one skill I didn't inherit :rolleyes:

That's cool man, especially at the time. That Super8 would be a blast to watch! Ken, if my old red car could come within' .10-.15 of your stick time, I'd be more than happy.
