old school tunnel ram and carbs question

[JoeG]

I'll back you up Frank on anything but the Shrunken Head.......

will even sneak a set of Southside Machine bars in for ya Frankie...or if you are really feeling Wild... I think I located a set of the lakewood bars for leaf spring cars the style that looked like the ones for Chevelles...the two bars and all the little angle pieces welded in..

Bud I have all the bolt on pieces for a Day 2 Deuce! Vintage Lakewood slapper bars with the correct rubber bumpers, NOS M/T valve covers with T-bolts, NOS Edlebrock Turantula intake, orange blade flex a lite fan blade, ET finned diff cover, need to get some headers and a Hurst T handle shifter, and lets not forget the CRAGERS!!!

I'm running Weiand straight linkage. Not progressive. I think the part number is 4011 or something like that. Both of my carbs come out to 780 cfm which even on a little 289 is more than is recommended but it is the smallest 4150 carb available from Holley.
BTW Running a Crane cam, very mild. But it produces a ton of vacuum and torque which is needed to run a tr on the street.

your getting me confused now you mention a 4150 carb "double pumper" then you mention a 4160 "vacum secondary.so what is better for my tunnel ram double pumpers or vacum secondary carbs. i don't think there is room on a TR1-X for 2 inline double pumper carbs.the vacum secondary carbs i've got now the bowls are seperated by less then a 1/2 inch between the front and rear carbs. so your saying a 600 cfm vacum secondary carb will be to much and i should go down to a 450cfm vacum secondary carb for better results.i bought 2 matched 600 cfm vac sec. carbs off of ebay for a good price and all they need is a rebuild. the camshaft that's in my motor right now is the GM #140 solid lifer cam and my compression is 11.5:1 and my rear gear is 3.73.

I don't think 2-600's are too big. The cam sounds appropriate. Need some good gears. JMO Sam

Correct me if I am wrong,but I always heard that vacuum secondary carbs did not work on tunnel ram setups because the tunnel ram decreases the vacuum on the engine!I remember a long time ago that my brother had to change out his carbs to non vacuum secondaries in order to get it to run correctly.

Motion had set up a 454 ZLX tr /(2)600cfm--513rear/hone---
Sam your right with the steeper gears with 1200cfm---But ....as Whitetop pointed out the smaller carbs just make life easier on the street--you could spend more time cruisin an less time tuning---JMHOX2----

VAC/MEC SEC---Would depend on cam/vac venturi size on carbs etc as whitetop pointed out and tr design--Whitetop seems to have a winning combo and you go with what works with your mods---

[JoeG]

Here's a photo of an edelbrock tr/(2) 600cfm carbs-str. linkage----From that Motion car---maybe this will help--Just some info
