Solid Cam, Use it or Not
106LSA, 244-249 @.050, 532/543 lift.
Street car, ported X heads, 750 Holley, 3.23 gears, 4 speed, RPM air gap. 69 Swinger 340
I'm pretty cheap too, even reusing head-gaskets.
But I'm not so cheap as to run a cam I can't put eyes on, and that one has my azz puckering. It may be good, IDK, but not from where I'm looking, and not enough to risk doing again in a few miles. So then I'll just say;
No way I would run it on the street in that combo.
===============================
Not to mention;
>it's too big anyway for a 2.66low 4speed and 3.23s.
>Not to mention how much gas that cam will suck, and the price of gas.................
> the slowest you can likely drive your Swinger without slipping the clutch, with that cam, is gonna be about 7 or 8 mph.
>And if the power starts at 4200rpm, that would be 39mph, where it starts.
and the peak might be 5400, so 50 mph. And if you shift at 6000, that is 56 mph.
>the bottom end is gonna rival a 318, and that is how it will take off every single time; even with the cylinder pressure maxed out for your X-heads..
I ran a hydraulic version similar to that; the mighty 292/292/108 with the 2.66low trans and 3.55s. That was a mistake. and within a few thousand miles I pulled it out. Here's the kicker; I ran it at 11.3Scr (alloy heads); and making over 185psi, in a 367.
Maybe you don't care about driving slow, but there are times when a 7 or 8 mph minimum speed is just way to fast. AND, 30mph in second with 3.23s is ~2320rpm, so your 340 will have 318 power down there and accelerating from there in Second, you can measure that on a sundial. So you'll be forced to downshift and hit ~3210, yippee, those 3.23s are killing it. Been there done that.
