327 ???'s

would a built 327 be good for the track, I have 3.27 gears and a th350. what cam,intake and carb combo would you recommend ??

I don't have the motor yet so I can't get casting numbers for the block or heads yet but I will by tomorrow night.

They used to be a great motor, I guess they haven't gotten any worse, just the engines around them have gotten better....

A F*rd flathead V8 used to be the fastest thing on the road. Is it a good track motor? Well, no worse than it ever was, just the competition has gotten a bit stiffer.

Lose the 3 anything gear if you want to try to make it competitive. The only way to get enough power out of it to make it beat a larger motor is to make it turn more RPMs. Set up the heads, carb, intake, & cam accordingly. Be prepared for all the usual spectacular high-RPM motor failures.

I suspect there's a reason why (a) you can pick up 327s for like free all day long nowadays; and (b) you don't see a whole lot of them at the track. I can't recall exactly what it is; it may have something to do wiht the fact that anything you can do to a 327, you can do to a 350; except that if you do it to a 350, you get 350/327, or about 1.07, times the results.

Of course, it's just a 4" block; so if it's a late-model one, i.e. large-journal, you can put a 350 crank in it. Some of the same castings were used for 302, 327, and 350 in 69.

If its a 68-69 large journal one I'd pick it up. They have factory forged cranks and are getting a little bit harder to find each day. I think it'd be really fun and different to build one. As previously stated you are going to need to make this thing rev in order to make power. That means you are going to need some gearing and a higher stall than you'd need with a bigger motor.

Now. 327 good for the track? Yeah, why not? 327 good for the street? Probably not. You'll really wished you had that low-end torque.

a LJ 327 isn't going to have a forged crank, the LJ 327s were dogs, 210 HP if i recall. all SJ cranks are forged.

Hey squeeks, If you actually have a large journal 327 crank dont lose it. Never run into it myself. From what i've heard the whole reason chevy went to LJ was so that they could run cheaper cast cranks. The 327 I put in my formula came from my 68 impala. It's a large journal cast crank 250hp 327.

Yeah I'm kinds thinking my 68 Impala 327 4-barrel had a cast crank too.... it could be that truck 327 2-barrels came with steel cranks, I don't know. There aren't a whloe lot of LJ steel 327 cranks in the world, that's a fact.

Never run into a forged 327 LJ crank before. I have 2 LJ 327's here at home from passenger cars and they both have cast cranks (Chevy II and Camaro).
