Putting together a nasty SBC

[Tacoma]

oooooh

well, if you need some stock heads, let me know. I would dig that in a Vicky.

 

[MikeGyver]

Greg, you should definitely make it happen.

I'm currently preparing for my small block build. All forged 383 turbo, for my '95 Camaro. Shooting for 600-700hp, should be fun.

I might, I might not... still have to see if I have the funds.

Your 383 sounds fun! Single turbo? I had a friend building a twin-turbo '65 Nova, he had lots of $$ into the engine & then abandoned the project. I really wanted to see that one run.

 

[waynehartwig]

But at least with a Ford, it has the correct firing order How's that for obscure...


Seriously, rat rod or not, the newer LS motors are THE best (but you know that already). If you want to keep it old school, put a carb on it. 450 is pretty easy to get out of a 5.7...

Yeah single turdbo.

lol not at 5000ft it's not, N/A anyways.
A 7 liter LS7 (the most powerful motor GM has made) won't even make that at this elevation.

 

[Tacoma]

That intercooler is tiny.

HA! LOL I dig it. Throw some Corvette rims on it and I'm in love.

 

[waynehartwig]

Then if an LS7 won't do it NA, then any other motor will be hard pressed as well.

 

[LT.]

Hard pressed, maybe, but it could be done. It would be very difficult if you are wanting to stay under the 400 ci. size. The other real catch would be to keep it NA and running on pump fuel. That is how a Rat Rod should be. Greg, shoot me a PM if you are looking to run more than 400 ci out of a small block. I may be able to head you in other directions if you are looking for big inch small blocks.

It could be done with an LS7 as well. Any motor can be built. But IMO the LS series has the best platform. And since there are so many of them on the market now, they are cheap and easy to find and because of it. No real reason to go with an old school SBC, unless you are looking for that old school look/feal. If that's the case, then there is nothing more old school than a 327

 

[mbryson]

......then there is nothing more old school than a 327

I've NEVER understood the fascination with that engine. It is a respectable performer, but it's not the silver bullet most people make it out to be. Almost any small block Chev can run well. A set of aftermarket heads/intake on a craptastic mid-70s 350 short block with a decent rebuild will run WELL. (but I'm a 400 small block guy... I like cubes and a 400 is just getting started)

Seems like big cubic inches = big dollars. I appreciate the offer, but I think for something like this I'd have to stick to a mostly-stock bore & stroke.

LS-based engines are hella cool and I'm a huge fan, but they have no place in a rat rod. I'm not going for a period-correct build either, but just an old-school SBC, similar to the one I built back in the day. No need for 600 HP, just a lumpy, healthy SBC that can spin 6500 RPM w/o complaining.

I had a 'buddy' that swore up & down that the 327 is his '68 Camaro was the fastest & most powerful SBC that Chevy ever built. My '71 Camaro had a wornout truck 400 that was stock inside. I did swap on my Dart intake and Holley 750 carb, and it had headers w/ Flowmasters, but that was it. He wanted to race so badly one night, it also happened to be the same day that I picked up my freshly-machined 355 from Strausburg Machine. I had a block, crank, pistons, etc... all the short-block parts for a motor in the trunk of my Camaro. We ran down the 1/4 Mile down by the Dump in Orem and I spanked him so badly it wasn't even a race. That 400 made killer torque and ran pretty well.

There was a Utah County family that loved 400's, their secret was building them with 6" rods. They were hard to beat, had a bunch of fast cars.

 

[Tacoma]

350's are a good start for a "real" engine. Any less cubes than belong in a 6-cylinder, or in a subcompact.

 

[anderson750]

IWhen I had my Camaro I used to drive around picking on Mustangs... :greg: Never lost to one, but embarrassed many.

I have a GT 500 that is ready for you to come pick on.

Where was it 15 yrs ago...

The 327 cu in (5.4 L) V8, introduced in 1962, had a bore and stroke of 4 in (102 mm) by 3.25 in. Power ranged from 250 hp (186 kW) L30 to 375 hp (280 kW) depending on the choice of carburetor or fuel injection, camshaft, cylinder heads, pistons and intake manifold. In 1962, the Duntov solid lifter cam versions produced 340 hp (254 kW), 344 lb·ft (466 N·m) with single Carter 4-brl, and 360 hp (268 kW), 352 lb·ft (477 N·m) with Rochester mechanical fuel injection. In 1964, horsepower increased to 365 hp (272 kW) for the now dubbed L76 version, and 375 hp (280 kW) for the fuel injected L84 respectively, making the L84 the most powerful naturally aspirated, single-cam, production small block V8 until the appearance of the 385 hp (287 kW), 385 lb·ft (522 N·m) Generation III LS6 in 2001. This block is one of three displacements that under went a major change in 1968/1969 when the main bearing size was increased from 2.30 to 2.45 inches (58.4–62.2 mm).

The stroke is smaller than the bore, making it a fast revving and high RPM capable motor, with high HP possibilities - easily. 375 hp out of a production small block, how cool is that! Not only did they do it, but they did it back in the 60's. ...And with only 327 cubes.

EDIT: to add the 400 from the same Wiki page

A 400 cu in (6.6 L) small-block was introduced in 1970 and produced for 10 years. It had a 4.125-inch (104.8 mm) bore and a 3.75-inch (95.3 mm) stroke. Initial output was 265 hp (198 kW) and was only available equipped with a 2-barrel carburetor. In 1974 a 4-barrel version of the 400 was introduced,while the 2-barrel version stopped production in 1975. 1976 was the last year that the 400 was used in a Chevrolet Passenger car, available in both the A-Body and B-Body line. While popular with circle-track racers, the engine was prone to cooling troubles if cylinder heads without steam holes were used. They mostly put out 250 hp stock. Due to the way the block was designed, the 2 bolt main engines were stronger than the 4 bolt versions. The 509 2 bolt main block is the most desirable 400 block.

I like the stroke/bore ratio, but again, they're not any kind of holy grail or anything. They are downright respectable, but so is an LT-1, 302 Z28, or any number of other early small block motors. There's also nothing at all wrong with an L98 (my personal favorite--and yes, they don't breathe super well above 4500-5000 RPM but they are a FUN driver motor---I'm not a big high RPM guy personally), LT1 or LS engine either.

The stroke/bore ratio is pretty sweet on a Chrysler 440, GM 427 and a number of other engines as well. There's just nothing that special about a 327 IMHO. IF they are built right (like ANY other engine), they are fairly impressive. I'd almost rather have a 350 than a 327, though. Just for the cubes again (but then again, a 377 or a 383 would be that much cooler than that---but take a 400, run it up to 413, 426,427 or ??? you dare and go rip your unibody Novamaro in half )


Then again, I'd still rather have a 1970 455 BuFord Stage 1 motor. I'll take the speed/torque and the AC.

I want a 355 or a 377, in a 240z.

 

[anderson750]

Wellllllllllll.........not in my garage and for that matter, not even in production.

 

[MikeGyver]

That's going to be a fun car, care to share the engine specs with the rest of the class?

The motor is a bone stock high mileage LT1 right now pushing 7psi. Doing an all forged 383, 3.75" crank and 30 over. Lower compression and about 15psi boost :busted:

my buddy has an old carbed, n/a 383 in an RX7, just ran a 12.93 at RMR lol
