Spec Carbureted Engines

[BADVENM]

You can do whatever you want with the timing, just have to specify what it is on the dyno sheet.

7.6.2 Timing tolerance shall be +/- 1 degree.

Going back to original object of the thread....is is legal for me to put a carb'd spec 350 in a 3rd Gen? I've read in other places on this forum through searches, that no 350 is allowed in 3rd gens and I quote "period" but they were talking about 350 TPI and I think those threads were at least 10 years old.

You'll hear this a lot... look at the rules.

Section 6.13 in part:
5.7 liter (350ci)
1. Holley carburetor 600cfm-4bbl #4776
2. Edelbrock Performer intake manifold #2101, #2104, #2116, #7116, #7516
3. GM Camshaft #24502476
4. GM L31 #12558060 or L30 #12552520/12558059 heads
5. GM OEM H.E.I. distributor (non-computer controlled)

And just keep asking questions...

If you are putting down 255/307 numbers then I would not spend another penny on the motor. The extra 5hp will equate to maybe a tenth of a second and will cost tons of money and time to get.

If you go the carb route on the 305, Bob Denton ran that motor very successfully in previous years in the Great Lakes region.

Yea I was thinking more of a fresh spare engine. I've been passed Bob Denton's contact info. But Im sure that money is better spent on tires/brakes.

Speaking of tires....did the previous rules limit the tires to 255 size RA1s? This car hasnt been raced in a few years, and he has like 16 wheels/tires all 255/40/16. Everyone is now running 275 RR? Probably a question for a separate thread. Regardless, Im sure the 255s will be great for DE.

I guess I had that coming.

I guess I had that coming.

Just part of the learning process.

I think you also had a question about tires - yes 17" usually the way to go now... up to 275. I might need to check the rules... (see what i did there???)

But you're welcome to BBQ...

If you have 255’s, burn them up.. learn Racecraft. Seat time... seat time... seat time...

We have 3 third gens in our region running carbed 350s. They all make good numbers and are stupid simple. The 350 with a LT1 T56 makes a pretty solid setup. Bryan White has been running this setup for several years and it has been very reliable. The downside is that some are actually on the high side of torque so you have to be careful of your exhaust configuration so as not to build too much torque. The other downside they are iron head iron block. Still waiting for someone to submit a RCR to allow the 80s corvette aluminum heads.
