<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: novadude</div><div class="ubbcode-body">Not sure I understand the &quot;lot of head to tame down&quot; comment. It's 422 ci. How does that runner CSA compare to a L72 427 rectangular port head? I'll bet it's still a much smaller port to feed the same size engine. If you cam it right, I don't see why you couldn't have a civil engine with those large ports. If it was a 327, that might be a different story. [img]<<GRAEMLIN_URL>>/smile.gif[/img] </div></div>

If the question you are asking is the CC's of the intake port, they are 227's. I believe the L72 840 heads to be in the high 200's if not higher. Certainly, there is more to the puzzle from SBC to BBC (i.e. valve angles)

The size of the engine should help quite a bit as well as the weight of the car.

You cannot compare runner cc's from different engine families, as port lengths are different. The engine response to CSA (cross sectional area) changes. It doesn't really care about cc's. cc's are just a convenient way to compare CSA changes, since the cylinder head intake port length is relatively fixed for a given engine family.

My point was that the cross sectional area of the BBC L72 head is HUGE compared to even a large aftermarket SBC head. No reason why a 422 SBC with a 227 cc head can't be as &quot;civil&quot; as a L72 427 BBC with even larger ports. [img]<<GRAEMLIN_URL>>/wink.gif[/img]

65 or 75cc chambers? I dont think the heads will be the issue as you can make them work with the right cam. Did you get a wear pattern on the gear during install? Also I assume you are running a cam button.. Couple other things.. When you pull the cam look at the gear. Does it have any burrs or sharp edges? That'll eat one up too. Also have you tried a slip collar distributor? Just curious if the block and/or intake stack up could be off and causing the gear failure.. Just throwing out ideas.. Its a really sweet ride and looks amazing. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

I cannot remember the size of the chambers Darrell. I'd have to look it up. The compression measured out to a calculated 10.6:1.

The pattern on the gear is good. It has a button in the timing cover and the &quot;walk&quot; was measured when it was built. It looks like there are more options that I did not know about (cam cores and distributor gears) when I wrote that reply. I can get a better core from Comp that will work with a melonized distributor gear. That should solve everything.

The wear on the bronze gear is normal from what I am told. I just hate seeing all of that crap float in the oil.

Thanks for the kind words guys. I am enjoying myself working on this car again.

Tim, this car should get into the very low 10's w/ a pair of slicks on.
Looks great

I'm working on the Nova this morning, getting ready to get the motor out...............and I'm about as far as I can go as I wait for someone to help me lift it out.

Not much I can do so, in lieu of getting into the beer, I'll post some pics.................

Parts have started to roll in. The hydraulic clutch set up, I frankly was never happy with. It always seeped brake fluid, and did not allow me to adjust the clutch as it wore (I probably have been a bit rough on the clutch [img]<<GRAEMLIN_URL>>/[/img])

I found this set up the mounts the slave like they do in the 1st and 2nd gen F bodies, should be much stronger than what I have mounted to the firewall.



I also found this slave set up. Rather than the slave in the bell housing, this mounts to 2 of the bell housing bolts...............and then utilizes a conventional fork and thus, adjustable.



I am going move away from a fixed proportioning valve, and install an adjustable for the rear brakes. This will allow me to clean up the plumbing as well. These 1st and 2nd gen Nova's are difficult to get full throttle out of. This Lokar pedal in a nice clean install and will solve any operational issues.

Had to do cable pedal too.

I found my victim here this morning......................Actually, Tracey helps me with this rather often.

She was actually glued to the Fezell cars (I DVR'ed the Saturday coverage)





And were out!
