"NO I just don't car to explain...plus I'm not an engineer...Have you ever held the upper TFS street heat intake in your hands before? If so you might have seen that clever design TFS engineers had when they made the cross section 15inch long...not too mention the way air has to traval over...
Yes, earlier clsoing intake will make more torque sooner and less overlap will make more power up high. These should equate to more power over a wider rpm range (area under curve). Also, the the tighter LSA (in your setup) is a closer match to what your setup requires. Both cams have both low...
The difference between the Street and Cobra intake is minimal! Yes the Street has slightly larger runners but not enough to even be concerned about. More importantly the runner lengths are almost identical...this is really where the intake design comes into play. Listen to the others on here...
For your parts the 112LSA has less emphasis on the exhaust, which the 165s don't need. It also closes intake earlier and opens exhaust later giving less overlap but still enough to keep idle issues from happening & making more power.
"Meaning if a car got dynoed w/ 3.55 gears and then had them changed to 4.10s, would he see different results in the dyno?"
Yes, assuming we're talking about a Dynojet dyno it measures the rate that you accelerate the drum (HP) throughout the rpms then it calculates the torque. You...
"The cam is 544 int, 555 ex. and my heads are 165 emissions legal 58cc, Anyone have any idea whether it will fit? "
It should fit with room to spare and it's NOT the max lift that causes the interference. Interference occurs near TDC when the vlv is just coming off seat on intake and going...
Overlap causes emissions and lumping. Does your X pipe have cats, if not good luck. If so any cam that has either 0 or negative overlap should pass. Some examples are Crane 2030, 2031, Crower 15510, Comp XE258, 266, 270.
"My concern is if a 112 L/S cam will idle right in my car?
Also I was looking at the NX264 cam. Is that a better cam as described "
Its the overlap that causes the idle issues (which happens to be a product of vlv specs) and neither XE270-12 or XE270-14 have that much that it would be a...
"So the bottom end looks good, should I check anything else? "
Casting doesn't create shavings but the CNCng AFR does does. You better make damn sure there's nothing else in there or it'll be coming out again real soon. It's much easier to tear down and clean now then later. At a minimum...
Heads and intake are a mismatch plus heads are killing you! 8.5:1cr isn't helping much either.
"Comp Cams .509/.512 268/280 dur. "
This doesn't really tell all that much, is the duration listed at 0.05" or seat, what's the LSA and ICL, hyd roller, solid, hyd flat?
