Likewise Tim! Keep me in mind for an L79!

That is a lot of cylinder head to try and tame down, and I would hate to not continue that valvtrain. Not clear on the bronze dizzy gear statement, we're you having problems?

Going back to the 5 speed makes sense, rather than cutting the seat. You can add a Hurst looking shifter and few will notice.

My ego would struggle changing a car you describe so flattering as setting the high water mark for speed in your stable. Wish you all the luck you need on the next phase of the project.HW38E

You are right Paul as far as the heads are concerned. My feeling, given the size of the engine, that should cover a fair amount. I have a cam in mind for this................but we are going back to the engine builder ultimately.

The bronze gear..............cannot get more than a summer out of it with a fair amount of debris in the oil, time to move on.

FWIW, yeah............my ego has a hard time taming this down. Again, the car is stupid fast and draws a crowd damn near every where we go.

The car is just silly fun [img]<<GRAEMLIN_URL>>/[/img]

Nice to see an update. Love this car!

Low-12s? Geez... That will be no problem at all!!

My '65 Chevy II has a mild 355 (9.6:1 CR, vortec heads, 217 @ .050&quot; cam, performer manifold, q-jet), a M20, and 3.36 gears.

I've had it at the track exactly ONE time with this combination. It was only my second time drag racing with a stick. With a soft launch (bog), and a Terrible 60 ft time (2.0), it ran 12.9x @ 108 mph. No powershifting.

11s should come easy for you!!

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]

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]

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.

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.

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]
