Small Block Pontiac 307

[Rod&Custom]

This is 68_Stang, I just changed internet providers, so got a new name. I am sad to say that the engine is STILL not at my house yet, due to multiple excuses. Doesn't stop the planning though, I am going to go with a 4 barrel air cleaner with a 2 barrel adapter,stock of some older camaro or such, and then if I get a 4 barrel later, I can still use my custom air cleaner. I say custom, because I plan to chop it all up, and run exhaust tubing(3") for a cold air intake, for better performance. Then I can fiberglass it until i like the look and shape.
Glad to be back on the forums!!

So do you have a 4 bbl. intake for that or not? I'd recommend not messing too much w/ fabbing a fancy air cleaner unless you have a decent intake. You can get an Edelbrock performer for 100 new or cheaper used.

And get that motor over to your place! Good luck.

Yea, I have a 4 barrel intake. Where can I get that edlbrock for $100? Sounds interesting if i can. Thanks, and I am working on the engine, will get it when the ground dries out.

Ok, so intake is ready to go. An edelbrock performer 4 bbl. intake is actually 109 through Jegs. Summitt is about the same. You can get a factory remanufactured Edelbrock 600 cfm 4 bbl. from Jegs for 180 w/ a manual choke. The Edelbrock carb is nice because you pretty much can just bolt it on and go w/o messing around w/ too many adjustments.

I noticed the last post was in February, is there still any life in this thread? Did you ever get the engine to your house?

Yep, the engine is at my house, and I have spent most of the day disassembling it. I have the block bare, and ready to get boiled. Still looking for that right cam. I saw that comp cams had a $100 cam and lifter set, but I think its over now. I don't know much about the specs of them, so I figured I better not just buy one. I want a bit of lope, but not to where its un-runnable. I am going to tackle the heads with a port & polish job soon, and she should be running like a champ! I just want it smooth, and able to smash those hondas! Write back soon.

Edelbrock is real good about selling cam packages that are matched to their manifolds. This is the way to go, IMO. Especially for a first engine. There's lots of other stuff to learn, and spend your time on other than wondering if the cam is matched to the rest of your application.

Great! Glad to see your back in the thread. I have pics, but can't post them because they are too big . Right now I am working on the heads, polishing the bowls, and porting the tunnels. I hope this will help it breathe easier. I have that 4-barrel manifold that I told you about, and I don't really have the money for another, so I hope this one is good enough. I still don't have the block miked yet though, so I'm kind of at a stand-still on it, which is why I was working the heads. Even though my dad hasn't had time to get my motor miked, I have still had some fun car-work. I am working at an old-timer's garage on a '49 Ford. It may not be the best car, but it gave me a chance to learn to weld with both gas, and ark. Hope it will turn out as a neat custom. Once again, thanks for the reply, maybe it will encourage me to get on it(the '49 has distracted me).

Can you post a picture of the '49? What a great way to start in the hobby!

Which 4-bbl manifold do you have, again? I'll search the thread, but is there a casting number, if it's stock?

Been so long I can't remember! (Happens as you age. )

Here are two links that I strongly recommend you print and study carefully.

http://vettenet.org/torquehp.html discusses the relationship between torque and horsepower.

http://www.dur.ac.uk/r.g.bower/PoM/pom/node12.html discusses 0 to 60 times.

It took me a few read-throughs before I really grasped it all. But it sure helps one understand what it takes to build a quick machine.

Happy reading!

Edit: Here's one more. http://www.headersbyed.com discusses the exhaust side of the engine. The $22 Header InfoPak is worth the price - it's a text book in itself! Explains some common mis-conceptions about headers, such as "bigger is better". It ain't true with cams or carbs, and it ain't true with headers either. Once again, the whole package must be matched together, for optimum performance.

I didn't see where I'd put these links in, earlier in this thread. Forgive me if it's a re-post.

Alright, I'll need a little time. That is alot of information. Very in-depth and valuable. Thanks
