Tuning a stock fox.?

[STROKD]

Get a pro-m mass air... 75 bullet if u can find one used (I have one for 24s if u r going to get injectors later)... Set tps to .99 and adjust the tb to idle car at about 900-1000 for best throttle response. Set base timing (with distributor spout disconnected) to 16 degrees, and run autolite 24s gapped at .055". That's about the best its gonna run till u mod it more.

I also have some bassani equal lengths I could sell yaif u want a nice header..

Tell Nick to hurry up, get his heads, the B25 I sold him and an edelbrock rpm or rpm2 and go run some 7s on motor...

So many people now talk about exhausts of PCM controlled engines. The exhaust affects the best needed air and fuel. Opening up the exhaust leans the mixture, which doesn't help most vehicles. It's hard for people to grasp that if they swap 3" exhaust in place of a 2.25" exhaust, that they must retune the PCM to realize the potential gains.

not true, it usually changes the map sensor so much the computer over compensates...............same with a good header on a carb'd engine, the draw on the carb gets stronger.........as well as the main jet. usually jetting goes down with a properly designed pipe.

Cross overs, who has them, likes or hates them, or cannot tell any difference? I see the "H" as more structural than anything else. The "X" is a novel idea, but it does force one exhaust mass into another, that's not ideal. I imagined the best 20+ years ago, seeing 360 degree headers for the first time. Take two pipes side by side, split the flow in half of each(reverse collector), one of each goes straight back, one swerves slightly over and up/under to get parallel to the other's pair pipe, and the four rejoin as collectors, no restrictions splitting or joining. That would reduce restriction from each bank, but it wouldn't quite scavenge like a header. The purpose of a collector should be to somehow efficiently get part of the flow from one bank to the other bank. The idea is to take advantage of the entire exhaust beyond the cross over, for each bank.

.

where do you guys get this garbage? 360 headers insure an even timing event when the pulse reaches the collector with equal tube lengths.....this is a problem that ONLY a 90 degree V8 has. this is why it's almost a waste of time to try a 4-2-1 on a V8 with a 90 degree crank. There are other reason's why it's a waste but we won't go into that here. How you fire the pipes into a 4-1 is also a BIG deal. inline 4 cylinders take advantage of evenly spaced firing orders to properly use a 4-2-1, firing order is each cylinder paired is 180 degrees apart.

Well i got the brodix heads already and figured the n41 would.be better for my setup
