Birdcatcher??

[sifocalpoint]

Ok heres the question, my dad has a friend who has a complete birdcatcher setup on a holley tunnel ram. It was setup to run alcohol but the guy has a boat load of parts and said he will convert it to gas.
Anyone run a naturally aspirated tunnel rammed gasoline bird catcher motor.
He can get it cheap cause hes good friends with this guy and they hook each other up, but is there a great performance differance over a carb? Reliability? Idle, overall performance from idle to wot.
The boat is not a race boat and will be a river rod for occasional blasts.
Just needed some opinions

No problem running it on gas at all once setup forget about it, the difference is "NIGHT AND DAY"!.. Are you sure it's a Holley manifold??, usually the Edelbrock Victor Ram is used for that setup???..Got a pic???..

If you your carb setup is correct there should be no difference on the top end. Fuel injectors are pretty "touchy" as far as using the throttle. In most cases fuel injectors are made to run wide open. If you want good all around performance stick with the carbs, unless you want to pop for an "EFI" system

Ahh c'mon now Dave you know they can work smoothe from idle on up and a lot more reliable!.. :D

Yes, I run one on a chevy, but its alcohol. The throttle response is second to none. I switched out 2 good running carbs for an injector and picked up 1.8 tenths with no other changes. So easy to change the mixture, just one pill change. Also, make sure the nozzels are plumbed into the manifold and are aiming down the runners. If the nozzels are way up in the hat it may be a different story...

Yep, same with gas the window is narrower that's all no biggie!.. Nozzles in the hat on a tunnelram deal does not work period, they have to be down low on the manifold!..

Be sure he puts the proper spool in the barrell valve or you will really chase your tail to make it run right. Call Endlerle for the right spool. Usually he has a number stamped on the end of the spool shaft for unblown deals.
My memory says the number "12" but....how good is my memory? :confused:

I forgot that part. I switched over a blown gas bird to the tunnel ram alcohol set-up and you HAVE to change the spool. The cut-out and the ramp are very different. Its a nominal amount of $, so dont let him skip that part.

This past World Finals some friends of my buddy where helping him clean out the nozzles, when they screwed the nozzles back in to the manifold they over tightened and spun the injectors facing upwards. It one crappy pass to figure it out. I never let people work on the motors, but cant stop that when your not there...

Spool, nozzles and pills all have to be changed!..
