Thanks guys. I got it out, but I wasn't so comfortable with how hard I had to hit.
Anyhow, tomorrow I'm going to pickup some taps to clean threads in the block . 7/16"-14 is the thread size for the heads, ya? 5/16"-18 for the front cover and intake stuff?

I have yet another question. I wonder if it is worth it to get an adjustable timing set so that I can set up the cam in the proper position. Someone I know, and whom I trust recommends the adjustable set, and I've been searching around a bit for others’ opinions, which largely seem to be in favor of adjustability. Example,
http://corner-carvers.com/forums/sho...9&postcount=11 Specifics of the engine combo can be seen in post #1 of this thread, http://www.streetstangs.net/showpost...64&postcount=1 and I plan on going with this cam http://www.cranecams.com/?show=brows...tType=camshaft plus a new torque converter/shift kit et cetera. Basically, what sort of power output differential will be likely between a properly degreed cam and one that suffers from the nominal rate of error?

Well, I decided to go with the fancy Cloyes Hex-A-Just adjustable timing set.
It uses an eccentric that rotates the sprocket on the camshaft. It requires an extra long dowel pin; a fact I didn't realize until AFTER I had put the too short pin in the cam. Left for advance, right for retard. I lined up the marks, like one would do with an ordinary timing set, and this is what I got at .050, intake open Cam card says intake open @ .050 should be at 1 degree BTDC. adjust, adjust, adjust... Everything is dead on to the specs on the card. I know the wheels looks off the last picture. I re-centered it, and all is good... I'm very happy with the results, but if I have to find TDC one more time...

Now, you did have a dial indicator on the lifter making sure that it was at .050 lift at the 1ยบ BTC sepcified on the card, right?
Glad to see someone actually "degreeing in" a cam. It does make a difference.

That's what they say. I wish I could get some real numbers on that though. [Rhetorical] This particular set was off by six degrees. Is that typical? I suppose I could have fixed that to within two degrees of correct with a standard multi-key way timing set. What is two or three degrees worth? Did I just pay $50 for 3 horsepower at 5900RPM? [/Rhetorical] If nothing else, I like learning stuff. So it was worth the money and time.

Well, that many degrees seems way off to me when they certainly must expect 90% of people to install it "dot-to-dot." That's why I wondered if your dial-indicator was giving you a true .050"
Please go over it one more time. Sorry. Also compare intake to exhaust, to see if the LSA and centerlines are as stated.
