Thank You I did it even without being talked through it. Not that computer smart.

Still working on car when able. Have been running wiring under hood for placement of all the extra electronics---CSR water pump---Derale Fans---MSD ignition. Just about only thing i need yet is the Derale PWM 66831 Power pack---Ram Concept 10.5 Dual Disk---Racetec has my order for pistons a few months back they are still in engineering---The one big thing is complete kit TKX with hydraulic clutch and drive shaft which I have not ordered yet. Dan Curtis let me know his crankshaft balancing shops he uses need to wait on pistons before going there. One of the shops balances without drilling with i would prefer.

Thanks again Larry

Ramzilla - might you be aware you can EDIT the title to this thread

and correct it to read STR-11 Intake ( Street Tunnel Ram )

rather than incorrectly having the title as "SRT-11"

Thanks for info motor still in car. Hot here in Az. Still gathering info on pistons rods cams valves valves springs. Still thinking about Fitech. Sure glad I joined forum would be lost without it. Anyone need to know about part no of factory parts I may be able to help since everything is still there. Saving all factory parts SC Rambler just in case. Maybe I can figure out how to send pictures. When and if I have time. I know cooler weather is coming.

Update - Jan & Feb 1969 AMC Hurst 1969 Nascar Javelin 305 CrossRam for DAYTONA

ran a pair of then BRAND NEW on the market HOLLEY LIST 4224 660 CFM "Centra-Flow",

subsequently better known as CENTER SQUIRTER 660's, Holley 4 Barrel 1-11/16" Dia Butterfly Carburetors !,

? How many Holley Carbs in Jan '69 had the Tarozzi Daytona Picture Visible 1:1 Cam Roller & Slot Linkage Bellcrank ?

as per 1969 vintage BOB TAROZZI, Hurst Staff Engineer COLOR PHOTOGRAPH at DAYTONA !,

and apparently maybe assigned Corp AMC GROUP 19 SERVICE PART NUMBER 448 8113 !

as mistakenly listed in the 1969 Hurst Super Stock AMX specific parts RWB Parts Manual Supplement.

Look Closely and Carefully at the bellow BOB TAROZZI color Photograph of '69 Hurst Nascar Javelin at DAYTONA...

Wow, in 1969 The Holley Carb Company was located a whopping 10 miles away from the

Hurst Performance Research Ferndale Location Building where the Nascar Javelins and

S/S AMX's were built...

And here is an Holley ad from Feb 1969 Hot Rod Magazine announcing the new for 1969

Thanks Holley's look nice good price to. Carburation is still up in the air. Even thought about Fitach. Almost done with front suspension cleanup need to paint a couple of parts yet and install bushings in a couple of parts. No rust but dirty underneath wheel wells Just want to clean it up. Not painting body parts. Still need to remove engine. Than can remove crossmember to cleanup and paint before installing frontend parts. Maybe should of removed motor the first thing. O WELL Just did not want to see motor out just sitting there staring at me!!!

No endorsement, just stumbled across them...

A used freshly rebuilt pair of "newer" Holley List 9776 450 cfm Tunnel Ram Carburetors

for sale on FaceBook MarketPlace asking $500 for the pair in Chattanooga TN...

Very much like the original Hurst SS AMX 585 CFM Holley List 4584 Carbs on the CrossRam only smaller.

Thought no harm in passing on the info regardless...

[QUOTE=SC397]

I built a 401 a couple of years ago with a Crossram and was limited on compression ratio and cam. Even with 9.5:1 compression ratio and a Comp 280H cam in it a pair of 600 Holleys were just right for it. We had it on a dyno watching for a lean or rich condition and it never ran rich.

What was the carb number on those 600 Holleys. Also were they Double pumpers. Thanks Ramzilla

A couple of questions on Doug Headers. For my SC Rambler Doug only lists D 109 1 5/8 inch primaries. Is there fitment issues with 1 3/4 & 1 7/8. Do you know what can be done if any to fit the larger dia. headers that are made for AMX. And will the ceramic headers run cooler. I am here in Arizona. Looks like Cal. is location of Doug products and Pertronix also. Looking into Pertronix ignition also. The new HP Moblie product. Thanks for any input Ramzilla

If you want the best set of headers buy a set of all stainless steel American Racing Headers. Many members here have already purchased them and ARH actually used members cars to build the prototypes off of. Yes, they will cost a few dollars, but you only have to buy them one time,you can choose the size you want, and regardless of tubing size they all fit perfectly. http://americanracingheaders.com/collections/amc
