I remember that my 69 Corvette 427/435 felt like it was barely on the ground at 145 mph. It had just enough lift to be a bad airplane. My 70 AMX topped out at about 125 and it was stable. Now, if it would have gone 145, who knows?
I’ll let you know! LOL

Re: Most aerodynamic Muscle Cars?

I just checked the CD (online source) and my ’70 AMC AMX is listed at .48 CD. Have no way of knowing current CD but the car is considerably lower than factory (have to lift the car to get a low profile floor jack under the front). That has to help the CD, right?
Interesting NASCAR article there.

Re: ETAPRO version 5.0

It looks like you don’t need engine dyno numbers. I do not see that transmission gear ratio (all forward gears; specifically I’m interested in manual transmission gear input) is asked for. Would like to see a program that user can input various gear ratios on transmission and rear-end and effect on ...

Re: Racing parts sales scams

Ive recently been posting FB ads on car parts and I state in the ad “if you want to, I’ll Face Time you with me and the parts”. I figure that should ad some level of assurance to the Buyer I’m for real. I also state “pick up the phone and talk to me about the parts and potential sale”. I find that p...

Re: No more King XP bearings

Went thru this tolerance issue on a 4.6 modular Ford during COVID. Three, maybe four sets of bearings I went thru before I got a set to work with mix-n-match. Was using King and Levite.

Re: stinger

I just bought a complete MRT ignition. The two boxes appear to be wired together as it was when pulled from the Peck and Peck Pro Stock Gremlin; a west coast AMC sponsored vehicle. Also came w/ a Chevrolet tach drive distributor grafted to an AMC lower section. I think that the distributor is transi...

Re: Prove it to me....Camshaft Gear Drive is a HP Killer

Yes, great article. Al are all of these “tech” articles, basically a sales pitch. But if you read it and put some common sense into your interpretations, then you should be able to discern the issues and benefits of a gear drive and 3-gear quality unit over a 4-gear that has obvious mechanical desig...

Re: Prove it to me....Camshaft Gear Drive is a HP Killer

I was at the speed shop yesterday. Milodon 3-gear drive: $560
ProForm 4-gear BBC $135. And what does one expect for 1/4 of the cost?

Re: Prove it to me....Camshaft Gear Drive is a HP Killer

Indy lite series (don’t remember the years) ran Buick V6’s exclusively and all had Milodon gear drives. Over 1,000,000 miles and not one failure attributed to gear drive “issues”

Re: Prove it to me....Camshaft Gear Drive is a HP Killer

Update on my Milodon Gear Drive: I have seen a lot of confusion on the internet about this so I thought I would ad this for posterity. Just degreed the cam today. This is the easiest deal in the world to degree. I used a 9” diameter Crane degree wheel instead of my monster sized Moroso so that I cou...

Re: Loud Exhaust

No, not enough room for resonators at the back end.
Yes to any of the Walker mufflers mentioned.
Something to think about....reproduction mufflers for a C-2 Corvette. Probably the quietest and still reasonable flow for that 360.

Chad, Those are some wildly shaped retainers, never seen that before. What is your coil bind clearance? I just had new springs put in and set at .050”, installed heights are 1.975" / 1.950", 390# / 1,000#. Found another 3 CFM while at it. What size are the headers going to be? Congratulati...

Thanks, Joel
My understanding is there are significant gains by doing so on Super Stock Hemi engines.

Re: Gain from lifter bore blueprinting?

It def would make power If there were no errors, how does power increase? I have never saw a factory block that was right. Probably best case scenario is find a block that has ran and shifted or settled ,then fix it. Most are horrible,angles off,location etc Amazingly, the AMC V-8 blocks have very ...

Re: Limit of a stock type oil pump

On my SS/G AMX, I have a Indy Cylinder Head timing cover with a Razor (integral to the timing cover, like a Buick) oil pump. Shifting at 8K. Tried all sorts of tricks to LOWER the pressure as it’s around 110-115#. Not just spring, spring adjustment, but a recirculating bypass type valve. Putting a s...
