Tunnel ram set up

Hi!! Put on a tunnel ram in January and have been tinckering with the tuneup,here are my results. 1932 glass 3 window,1987 302 ford with a b cam and gt40p heads(used craiglist motor) stock fuel pump,weiand tunnel ram with 2 390 cfm holley carbs(new),5spd m5r2 trans(truck),355 posi,car weight is 2640 with me in it.stock jets are #51-.050 hole,went to a #66-.066 hole on the front carb and a #67-.068 hole on the rear carb(the front plugs were burning different than the back) 6.5 power valves in both,purple sec spring,# 28 squirters,timing at 10 before TDC-34 total. Manual chokes on both(don,t really need them,3 pushes on the gas when cold fires up,after warm up no push on the gas is needed,fires up) At idle it has 20 vac,on the highway 12vac. I,m pleasantly surprised the way it runs,no bogs,not temperamental,it plain runs great!!I,v driven it in30 degree weather up to 90 degrees. I think the lightness of the car and the manual trans help the tunnel ram on the street. Pete

Forgot to add the headers are limefires(with powercaps) from Sanderson that dump into 2.5 pipes thru smithys mufflers ooooout the back. the fuel idle mixture screw are 3/4 turn out. It idles at 800rpms(had to back out the secondary throttle plate adjustment screws 1/4 turn to bring down the idle ,the primary idle screw was all the way down) 2 OBG air cleaners.

Do you have a photo you can post?

Hey Thanks!! I,ll have to have my son do a video(computer handicapped) Pete Your avatar truck looks mighty nice also!!

That's Bitchin'! I keep mulling over doing the same thing with my 302.... Glad to hear yours has worked well so far. Can't wait for the video.

Very nicely done setup, looks great and runs good too!!! Hard to beat that! Oh yeah, and a Ford in a Ford just helps to make things right in the world!!!!!!

Can I ask what the color is on the pick-up? Is that Washington Blue?

You're most welcome!!!

Now, if I could find a streetable tunnel ram intake to work on a Clevor, I've got just the project to put it in!!!!!!!!!!!;););):D

NICE!! She's a great runner! Looks like you got the tune set about perfect. That's great, gives me some encourangment to do mine with dual quads.

Good working setup!

That was a nice ride , thanks for taking the time to do that. you sure do have it set up dead on it sounded perfect no hesitation at all. I ran a across a dual quad set up on craigslist with carbs for a good price now I need to get my but in gear.
Congratulations on the nice ride and I like the truck in the background also in post #4

Cool. Thank you for posting the ride-along. That was fun!

Thanks!! A couple of things(mistakes) I learned when tuning the carbs is to get the primary circuit correct first(jets),I made the mistake of increasing the squirters to get rid of the low end bog(was up to a #37)but when at highway speed it was way to lean(the squirter helps with the transfer from idle circuit to primary circuit)I am down to a # 28 squirter now). Jets-4 jets from summit cost $14+ and holley suggest to jump 2 sizes at a time(that could be alot of jets if you don,t have access to jets)local drag racer gave me his drill set #1-50,told me to drill the jets a thousand,s at a time till I got where I need to be(holley does not recommend drilling jets) You can always buy the correct jets after you dial it in. Hope that makes any sense.A vacumn gauge is a must(lets you know while you are driving when your power valve is opening)You do not want it to be opening while at highway speeds(power valve is to help make the transfer from primary circuit to secondary circuit) spring in vac diaphragm.

Thanks for posting the details, Pete. Makes perfect sense, and drilling out the jets (using a hand pin vise, I assume) seems like the only way to go unless one had access to a full range of "loaner" jets to play with. The vacuum gauge comment is a very good tip for the power valve, too. I like the clarification that the power valve is like the "squirters", but for the primary/secondary transition. Great video, too.

I found Holley carbs not overly difficult to tune. You simply have to learn how each part functions in the scheme of things and make adjustments accordingly. Now, with the advent of O2 sensors and gauges, tuning has become more precise.

Have you tried to run it progressive linked??

Hey!! No dont think that would work,right now the front carb is is jetted leaner by one size,the set up right now is real good. It seem by the color of the plugs that the front carb takes care of the front four cylinders and the back carb does the back four. Pete

Hey Roger!! Yes drilling using a hand pin vise-they are very small bits-would break easily. I use my 18 volt dewalt to hold the bit then turn the jet around the bit a thousandth at a time(takes a while to do 4 but its free) I was lucky to find 2 mechanics and drag racers who love carbs and explained them to me,told me the steps and it worked out,I hope I explained it well enough so a hobbyist like myself can tune a carb. Thanks Pete

That is an awesome ride you have there, and thanks for the video! I love the Ford in a Ford too, and the tunnel ram is the icing on the cake. Nice job!

Yes, nice job.....Im getting ready to put duals on my small block.....was wondering about using the Holley 450's vrs the 390's....what intake is that? Weiand?

I would advise using 390's rather than 450's for a small block. You don't need to flow that much air.
