Can you guys help me figure out my Compression ratio

That is not a very small cam
308/318/114/.488/510 lift
and 050 of 234/244

You are gonna need more compression
And more lotsa things.
I get a 82*ICA for a DCR of 7.2@ Scr of 10.7. Your target Dcr should be much closer to 9 or a bit better, to pick up the lower end.I ran 8.75Dcr on 87E10.
Unless you are racing, you will need to rethink that choice. That is a terrible street cam. This cam will be a ripper after 5000. But the getting there will need all kinds of help; from a big TC, and big gears; to, some special tuning skilz, and don't forget all the oiling mods to keep that beast alive at over 7000. If you short shift it, guys with smaller combos could/will be driving around you..With 3.55s and a 2.45 low ,5000 is 46 mph.I'd like to say the cam has lazy ramps, but that would be an understatement. If it sounds like I'm ragging on that cam, it's cuz I am. That is not for street. That cam is for idling around the parking lot and trying to scare guys with higher intensity cams. If that's what you are after, and you are a whiz at tuning, then this will be perfect; just know your limitations.....I ran a 292/508/108 @ 8.54Dcr, and that thing was very lazy with a stick and a starter gear of 9.44. That cam needed a starter gear of 12/1 or better, just to get out of it's own way, off-the-line.I cannot imagine it at 7.2. I got rid of it in a hurry.
With a 10.7Scr you need a high-intensity/ fast rate cam of about 268 advertised.This will pick up your Dcr to 8.7( on a 112LDA for the automatic).This might be a 223 to 226 cam, depending on who you buy it from.It will be 7 million times better a street cam. Well maybe not 7 million, but you get the Idea. Properly combo'ed that thing will be a beast to 65 mph and really strong to 85/95
I know what you're thinking ;223 is a wiener cam.
Well, I had a 223 cam, and I can assure you there was nothing wiener about it.That cam had the strongest bottom end of the three I have installed.It was also the most funnest
Whatever you decide, enjoy the ride!
