If I remember correctly you multiply your eighth mile time by 1.57 to give you a quarter mile ET.

9.79 / 1.57 = 15.37

Holy crap what kind of track is that Laughing I'm guessing Kenny Bernstien doesnt come by much (J/K!)
We have one hidden in the top of Indiana where the rules are, well, not really there. This reminds me of that place!

Great to see your having fun with the ole Burb. Thats not slow for a two ton cast iron beast-I bet you surprise a LOT of people with that!

A couple of people that race pretty regularly thought I had a big block in there. Laughing Not yet, but either a 427 or a 496 is in the works, havent decided which way to go yet. I want to see if I can get my 60' time down some. I have a 2.28 + or - .01 right now, and I want to get at least under 2. My dad has a 66 impala ss with a bone stock 20 year old 454 and a muncie out of a vette, he runs the same mph as me 73 to 75 at the end, but he is close to a whole second quicker than me. His 60' is in the 1.90s that is the only place I can see the time coming from.
I just pulled my tranny back out about a month ago due to a cracked flex plate, and happened to just have a 2800 stall laying around so I put that in at the same time. Between the stall and im going to go 4-5 inches shorter on tire, I think I should be able to get under 2, hopefully Confused

That "track" is actually an air strip at a rural airport we have a whole circuit of airport drag racing Laughing We only have 1 actual track that is still only 1/8 mile but it is at least IHRA certified. The closest NHRA track is a little over 200 miles away in Sabin, MN, and there is another 1/4 mile track in Lemmon SD. I guess you could say we make due with what we have, and it sure beats going out on the street and getting tickets that I cant afford, or worse, take somebody out.

Why not compromise and build a 499 (498.57 cid) BBC with a 4.6" bore block and a 3.75" stroke crank out of a 427. Have the best of both worlds with a Pro Stock motor that shifts at 10,000 RPM and yet pushes 500 cubic inches.

I wouldn't recommend the 15.7:1 compression version for the street though. Another plus the tunnel ram stays under the hood with none of those pesky scoops hiding the view of jaws dropping.

Seriously if you are thinking of building a BBC engine from scratch this combination though, unusual is viable, even in the suburban.

I don't mean to sound different. If you run a 1/4 mile time that is a number. if you run an 1/8 mile time that is a number. how can you say if I run sutch at 1/8 I will run sutch at 1/4. That is the asking too much If I say. Sorry guys #s work for me.

I really like that idea dave, but I already have 10 454 cores to start from,
plus I already have 3 factory forged steel 3.76 stroke cranks, an engine builder in town here said those cranks will support up to 1,000hp, that is why I was thinking of the 427, plus that is my favorite engine of all time.
On the other hand, there is the bigger is better mentality where as I can still use one of the stock blocks, stroke it to 4.25, and bore it to 4.311 and make a 496, which I also like the sound of. Then I could also make a 511 with the 4.25 stroke and +.125 pistons. Shocked

Unless your drilling for water 0.125" overbore is a bit much for a thin wall 454 block (actually 0.060" is pushing your luck). Now if you talking sleeving a 454 block were back with the 4.600" bore size as an option again.

On another tack are you familiar with the 409 chevy engines? They had a bore as big as Texas with a cave mouse length stroke. Their demise was caused by a lack of knowledge of metallurgy (rear ends, transmissions, or 409 block bottom ends tended to part ways). Good news is, any 409's that's still alive today has a (pretested) strong bottom end, and everything from the fly wheel back is stronger now (thanks to the 409). The other thing that held the 409 back were small heads, but that really made them a terror on the street. Not that I would attempt to tempt you into putting an engine that disappeared from the engine line up only one year before your truck was built (but people are already accusing of big inch deception). But since I can not tempt you: I move on.

The engineers at Chevy, and I have always been big fans of over square engines. The original Mark IV 396 was built and tested with both 409 bore and stroke (4.313" x 3.460"), and the 4.125" x 3.760" that went into production (because it offered more bottom end torque with rectangular port heads; the only option available at the time). The CanAm 430cid 7.0 liter all aluminum block was another big bore (4.400" x 3.470") short stroke terror (once again the all aluminum block had metallurgical issues now resolved with alloys; they fixed the problem with steel cylinder liners). Then comes the Gen VI big bore thin wall series of short deck blocks. Bore is safely limited to 4.500" unless you wish to invest in steel sleeves, though many have let 'er rip with a boring bar to 4.560" running 0.090" over leaves a very thin cylinder in need of hard pour. That means with a 4.500" bore and 4.313" stroke you can have 555cid of mayhem sitting in a 396 labeled package.

I built a 582cid which is as big as you can go in a short deck block but it wasn't worth the expense, for the difference in cubes, go with a standard configuration. But if I hadn't done that I couldn't tell you not to, so in that regards it was worth something.

Maybe it is just that I like shifting big blocks at 8,000 RPM, and having them stay together, even if nothing down stream does. I am just reliving the glory days of the 409 in a full size Chevy, looking for the modern equivalent of the 289 Mustang, or an unsuspecting 327 Camaro.

My buddy had a couple 348s and a 409, he rebuilt the 409 and hardly bought any new parts for it, most was reused and he had over $2,000 in it already, it was probably a 350 hp 409 with the heads and cam he had. So you have a basically stock engine with mostly used parts in it for the tune of $2,000, not exactly what I am looking for. Dont get me wrong it had gobs of torque and revved to the moon, but I dont have that much money to stick into an engine that will be marginal at best in quality and still only have 350 hp.
The machine shop I work in used to build engines for the roundy round racers back when they ran big blocks, there were a couple guys that found there was a couple casting numbers that were thicker than the others and they were bored +.125, ran 14:1 compression, 7200rpm all night and the engine would run a whole season before refreshing, im not saying its the best option, im just saying it could be done and could work provided it is the right block casting and there is no core shift.
In the end I will probably go with the 427 since I already have 3 forged cranks for that engine and after all it is my favorite. I know they say there is no replacement for displacement, but I think forced induction more than replaces it. Dave Thank you for the reply and info, coby

Your 0.125" over block and a 427 crank yields a 446 CID. Which is definitely an over square design in the spirit of the 409 I loved so in the good old days. Just breathes better with Mark IV heads.

So were both on the same page. It is the over square engine I favor not the 409 which is a collector piece now.
