Horsepower falls over at 5200 on the dyno so that's where I shift. I will have to get the new heads and go from there. I know an intake and carb are not the only thing that makes power, but I like doing the easy stuff first.:beers2:
your going to want to look at another cam to compliment your new heads and better flowing intake. a cam is usually selected based on head flow numbers. better heads will help build more hp and torque with your current combination but may not increase how high you can spin the engine and still make power with the current camshaft. what rpm does your toque peak at?
What's the diameter of the primary tubes on the Hookers? ...Man, that didn't sound quite right now that I've read that back.... :shock: Devon
1 3/4 Primary tubes on the hookers. What cam do you think I should use? I know I need more lift with the high flowing heads, and that is why I just ordered the 1.65 rockers from TA. However, I still want this thing to idle well in traffic, and cruise down the interstate getting decent mileage, so I am resistant to put in more cam. Sean's NA 350 made 400 HP with a TA 212 cam, home ported heads, and 1000 CFM carb. With the increased lift from the roller rockers and the X-Factor I should make a little bit more.
Damn....i just sat here and read all 6 pages of this thread. Much props to you Cason, as you are doin an awesome job on ur car. Wish i was that productive on my car. Keep up the good work :TU:
Got two problems...no money...only know car basics...haha. I need some one to teach me all they know :beers2:
Well this board has helped me lot. I remember how it started for me. I thought "I can put a 4 barrel carb on this 2 barrel manifold. Yeah, that'll make it go faster." Few months later, I think I need the 4 barrel manifold. Then I wanted headers, then cam, ect. It doesn't end.:3gears:
Yea, this board does help, just not with the experience part. Thinkin im just too nervous too mess w/ stuff i dont know about and end up messing it up, since my car runs fine as a driver. The reason i wanted to change to 4bbl is cuz i have to replace the valley pan soon due to a leak and it would be a good time to go ahead and do the conversion, that way i dont have to take the 2bbl back off and redo it again with the 4bbl later.
Good call, might want to block your exhaust crossovers while you have the intake off. All you do is tap in 3/4 inch freeze plugs in 4 holes on the heads and it will dramatically reduce how hot your intake gets.
Just remember you can't have your cake and eat it too . If you look around there are more than just Mustangs out prowling around . :boring:
Yes, I believe the good out weighs the bad though. 4 out of 5 race cars here are mustangs. I'm sick of them!
If you are running the X factor you don't have to worry about it . If you are running a stock intake and don't re-tune for the cooler mixture , more problems than you can figure .
Well, that gave me a good laugh. :laugh: Cason, I'm watching your combination carefully. I appreciate all the trouble you're going through to make your parts work as best as possible. My car is my daily driver, too, and the block has not been opened up, yet. When I go for a cam swap, though, I think it's daily driver status will be shuffled to weeknight and weekend sleeper. Good luck! :TU:
Here are the details on the heads which will be arriving Wed. and going to the track Sunday! I will be using the stock intake first, and since I move to college the 14th I'm not sure if I'll have a chance to try the X-Factor before then. I'll still be ready for a serious burnout down Fraternity Lane though.:TU:Thanks to the board member who prepared these heads for me.

I hate to dissapoint you but those valve sizes are stock , nothing special there . Now if you had a camshaft to support the head flow numbers it would help .
didn't the 73 or 74 go to 1.55 exhaust ? I do stand corrected on stock intake valve , all mine have been 1.94 .
