Ok need to fuel the new motor
Keith Craft 347, TEA (total engine airflow) number 3 ultradyne cam, same cam Brian Tooley's cousin Sammy Vincent was going 6's with(1/8 mile back in the day) marcus warrick ported them as a favor for the last owner, my buddy curtis, They worked and drag raced together about 14/15 years ago when TEA was in a quansent hut in Bowling Green and was called Tooley engine airflow. Edelbrock small valve heads, Its a 10:1 arp studed top and bottom with a girdle and right now has a 780 vacuum secondary from a cobra jet(flows like 735) but I'm pulling it and running the GT40 intake I have with the 65 throttle body and adjustible regulator. My buddy curtis says I need at least 42's. This motor with street heats and an x303 went 6.0's at 105 on motor back in 95.

These heads don't have the port ve or volume to run with the street heads but should be in the high 6's low 7's on motor and have a deal working for a GT4088 the car may be a turbo rocket real soon. But for now do you think the 42's would be enough.

You might get by with 30#s but 42#s will definately do it.

That GT40 intake is going to be too small for that engine. 42lb injectors will probably be perfect but if you plan on using a stock computer you are probably going to run into start up flooding issues with that big of an injector. A solution is to run a PMS or some other piggyback system which that engine will benefit from anyway.

High 6s to low 7s should be no problem with that engine. I highly doubt it went 6.0s with Street Heats and an X cam back in the 90s. 6.0 in the 1/8 is about a 9.45 in the 1/4. Without a power adder that combination won't make enough power to run that number unless it was in a 1500 pound rail car.

Hey Darrell I was reading this and just wondering what happens if you are running to much fuel for the intake. say a small one like the GT40? Will it backfire or stall or what? I was just wondering thanks.

[JBIGBOOTSY]

startup, part throttle driveability problems.

The intake won't make a difference as far as fuel delivery but a GT40 intake doesn't flow enough air for the engine he has. He will be leaving power under the table with that intake.

Now running an injector larger than a 36lb on a stock computer usually causes start up problems because it dumps too much fuel in when cranking. The stock computer doesn't know how to reduce fuel at start up. Usually you can just put the gas pedal to the floor when starting the engine to get around this issue but it gets to be a pain in the ass.

If my buddy had a way to load old vhs tape videos to street fire I could show you. The old streetheat high ports that were on the car were 2.08 intake valves and 2.05 on the exhaust. The flow numbers were crazy up past 325 on the intake . With these old heads on this motor with a 750 double pumper was in a full bodied full interior 85 car on DOT's. It went constant 6.8's for like 2 seasons around Middle TN area and the last track day of the year bolted on slicks and went 6.04 at 105, The last owner does have wheel stand pictures to prove it. I'll see if he can find videos of scott's or sammy's car to prove it.

I think you misunderstood the valve sizes. There isn't a small block Ford head out there that has a 2.05 exhaust valve. I am familiar with the old Street Heat heads, Sam Vincent and Brian Tooley. I know Brian fairly well and do alot of business with him. I also know that Sam Vincent is a nitrous freak and any engine in his car is highly intoxicated on nitrous. The old Street Heats were good heads back in the day because they were pretty much all there was for Fords but they don't have real impressive flow numbers, even in ported form. You said yourself that the heads in question only flow 325cfm or so which is equivalent to a set of bowl blended R-series heads. I know a 347 is capable of running 6.0s, I've run 347s in my cars over the years. But the X cam isn't going to get the job done. That combination was probably making about 450hp. To run 6.0s in a 3000 pound car you are going to need about 750hp. Look around and see what the rest of the guys running those times have for combinations and you will understand what I am talking about. One way or another someone is not telling you the whole story about this set up.

Heres a recent video of what sammy is doing, The rear end in the car I'm buying actually came from his 93 notch when he had the liberty shifted tremec before he bought the g force. You have to remember these guys were doing this back in the day and had to be doing something to be able to graduate up to the insanity level now.

My bad they were 1.65 exhaust. I'll see if Curtis can go high tech and film his tv and load some of the videos...

1.65 makes more sense. That is fine if you can post some videos but that is only going to show a car going 6.0s, its not going to show what is inside the engine or under the hood. Without a power adder that engine that you described will not run anywhere near 6.0s in a full weight door car.

^that was curtis typing,
I think if I dont get on the motor for a little while and break it in that the 24's I have in there will be ok and will allow for enough fuel, darrell what do u think?

I dont think I would waste the time w/ 24s. With the elevated pressure you will have to run you will be pushing the injector close to max duty cycle.

ahh yeah i didnt even think about that thanks, so another question what type of computer would u suggest and also what type of intake? I am not looking for the best of the best u know I was going to have the gt40 ported and also get some type of management system for the ecu but I dont know really anything about going "big" with ur engine.

For intakes maybe systemax or rpm2. As for tuning depends on if you are going to self tune or just take it to a dyno. If you are going to self tune you have quit a few options, Anderson PMS, tweecer, AEM, FAST, Big Stuff ect..

[Sleeper_Stang_89]

I run 30# injectors and they are at almost 97% duty cycle... on a DD MILD 331
