    Car Dynoed! #'s inside!

    Well, first of all, I must say I am pleased with the numbers because of the factors my motor has. The low compression didn't help, and other obvious things didnt help either... The cookie contest was really close! (in talk section) :D

    Pro Topline Head users. FEEDBACK?

    I just wanted to start a feedback thread for Protopline cylinder heads. I own a pair, they are currently on my car and I love them for how mismatched my combo is N/A. Lets just say I have some traction issues. Has anyone got their car on a dyno yet with their cylinder heads? I'm going to...

    pops out exhaust on decel...

    Seems like it is poping out the exhaust on deceleration. and when i give it just enough gas to keep a steady speed it pushes and pulls. I'm not sure if it is a misfire or not. timing is 13*, fp is at 38 vac on. tps is at .98 and idle wants to jump around a bit. Any ideas? Also, I hear a...

    Can't get into 1, 3, 5 (and second is squirly too)

    This only happens when the tranny is hot. My clutch cable sounds allitle weird and the clutch releases pretty close to the floor. The problem i had last time was tightening it too much, and it would slip the clutch. Did i install the cable wrong? Does anyone know where to route it? How much...

    New heads, acc. bracket stud does not screw in? hole too large in head?

    This kindof makes me mad. I buy new heads, and I am evidently going to need some type of thread insert for the both sides. The stud for the a/c / p/s pump will not go into the head because the threads are way too large. same with one of my bolts on the alt bracket. What size do I need? This...

    Do I need to wait on a 75mm TBODY gasket?

    I just wondered if there was alternatives to not using a tbody gasket. Would rtv black hi temp silcone work? I really dont want to wait that long until I fire up the motor. Im getting the jitters. :flag: :nice:

    Just like the title says. I just got my PTL 180's in today and I want to do some minor clean up, and polish the intake and exhaust sides. :shrug:

    Serious Discussion: Velocity vs. Amount of air available

    I am some what confused. I realize that velocity is important in that it fills the cylinders faster. It also creates a vacume to keep more air coming. In doing so, I would guess that since the air is entering the cylinder faster, it is getting more air in the cylinder hense making more power...

    Parts, ported gt40 intake (tmoss) 75mm tbody, f303 cam, 64cc 180 protoplines, MAHLE forged flatops @ 8.7:1 compression ratio. and everything in sig... Im afraid that with the compression ratio that it has it will be a dog. What do you all think?

    would putting allitle hard block in my block be bad?

    I was thinking less than a 1/4 hard block. I don't want to run into cooling issues. Does this stuff actually make your block that much stronger? If so, how much? Is it worth it? :shrug:
