Didn't you just tell me to shut up about the mags? It applies to you too.

Rodney that's going to be one fine ride! Can't wait to see the video of the dyno session.

[philminotti]

Great numbers rodney. You obviously ran into the same limitations that keith encountered on his big inch twin paxton motor. Should be plenty to scare the snot out of you! Still though, I'd love to see what one of these modern strokers with state of the FE art CNC heads would do with a monster 8-71 blower sitting in top of it!!

[rodneym]

I think Chas' last post hit the nail on the head. Every damn word.
Except for hoople. The only thing I know about hoople is that Mott was one.

Stentor - Running BBs and Avons. If only one set were magnesium...

Patrickt - I never got around to Kirkham about it but I will. But after seeing what's been done with the 720HP Kirkham at the strip, I'm not overly concerned.

Phil - Yup, same limitations as Keith on those purdy relics.

Your engine looks great! I have a couple of those old Paxtons out in the garage. Maybe one day I can put a twin s/c set-up together.

This is an awesome project. Tom Lucas is an excellent builder; he built a great engine for me. It has 1300 miles and runs great. He was also outstanding during debug. He deserves more attention on this forum than he gets. In terms of the Kirkham drivetrain, as others have pointed out it is extremely well engineered and pretty well bulletproof. In this case, you do get what you pay for. I hope to see your car in person at some point.

Way cool !!

The Kirkham Super Snake had me itching, so I contacted Tom Lucas.

The news I got was, "the engine is in"...."a few mods left"....and Chas, are you reading..."it FITS under the stock hood!"

Here's a pic...

Yes I am Dude.
Another reason to consider the fans Rick uses to vent underhood.
Ask Tom if he cleaned-up the runners in that Dove T/W-mine was full of casting slag and needed port matching. You're pumping a minor tornado through it.
Like The Police; "I'll be watching you..."

[RodKnock]

Phew! I'm not a big fan of the bigger hood.

Good stuff Rodney.

[RodKnock]

First, I'm no expert.

But when I had my engine and tranny installed, the shop recommended some vents with screens be installed into the front fender wells. The shop owner, whose shop had many original CSX 3000's regularly go through there, said that they were installed on Comp and/or S/C cars. In any case they do offer another venting opportunity for you.

Additionally, they installed these air scoops with screens inside the nose of the car to help collect the incoming air more efficiently.

Install looks great in person, Rodney, just like it was designed for that car.

Compliments to Tom

Rodney,
I know it's not critical to your build but, any idea how much weight the Paxs plus all needed brackets, pulleys and etc. added to a 'standard' FE build? Did Tom weigh the components?

[rodneym]

Chas,
I've read that the SN60s are 24 lbs each.
The brackets were all aluminum (minus a small stainless one), carb hats, tensioner and spacer (for the crank pulley).
Maybe 65-70 lbs total?

We didn't even think to weigh them.

[ERA Chas]

'We' would have if I was 'Project Chief'.

I just always wondered. These on a Cammer with iron heads would materially change handling on our 90" wb. Certainly would need more spring and bigger bar at the least. You don't have such worries.

Next puzzle-how ya gonna get a timing light beam through that conglomeration??

.

[rodneym]

Just polish up those panels till they're mirror smoove.

That was an easy one.

Well, I finally got her home. I took her out for a spin. WOW! The amount of power on tap is indescribable, and that's with the shoe off and the pinky toe on the throttle.
It took a good amount of work:
Tom Lucas' (FE Specialties) 511 FE
Fitting and mounting the dual Paxtons (CAD design)
Beefed up fuel delivery
Moving the brake lines
The gauge cluster
a few tricks up Tom's sleeve...
...and it all fit under the stock hood (just a little messaging of the scoop hole)!
Tom did it all BTW.
It's actually very streetable, just have to be cautious not to sneeze or have restless leg syndrome.
The, shall we say, passing power, is quite a treat.

Let me know when you're in LA, Chas. I'm taking you for a ride.

There's a new pic in my album, btw.

Will there be some mags joining the whole ensemble?

You know Knockers, a Cammer will produce the same feeling...

[patrickt]

That is super-cool. How does it feel at low speed when you're just, say, pulling out of the driveway and heading down the street? Can you ease out in to traffic, or does it require a completely different driving style?
