Better to read a thread, check the dates, and make an intelligent guesstimate as to whether it is still active/applicable... whether the OP is still interested... any member can do a search themselves if there is old info they need...

We know who you are, just wanted to hear from you what your intentions are.
If your intentions are to cause problems we will solve them, I hope your intentions are otherwise...like helping others who post with your experience.
After all, thats what this place is for right, not for agendas or creating havoc or creating issues for the moderation staff right?
If you were a moderator what would you do?
|03-20-2018 10:10 PM|
Sir, i guess you are right.
Thank you for your candid observations.
I posted on this board for years and was asked to be a moderator. I declined.
Ive always been under the impression that people might actually read these threads to try to learn something. But I guess that I might be the only one that actually reads this stuff.
Rest assured Mr. Moderator that I will refrain from future posting on anything older than..... 3 days?
It might be expedient to put an automatic thread delete to threads older than 30 days.

HotRodRay63 You seem to be on a mission posting on old threads you dig up, how many pages back did you have to go to find this one...10?
Whats the point?

Gee Chuck. Looks to me that Nov 17, 2017 to Mar 20 is 4 months.
Ive been around 50 years and still learn some things.
Anyway, I look through oooold threads trying to learn something and sometimes post to help somebody else. Like starfish.
Maybe threads should be deleted completely when they get a few months old. Naw...
Today I looked at a freshly assembled 302 INstalled a car, not yet run, and the right head gasket is on backwards. They said I was nuts.

Another old thread, look at the original posting date before responding.
A year old!

I conclude from the OPs rocker arm question that he has a pre 74 heads now... using either GT head will knock almost one full number off the compression, worse than the old 351 head swap of 40 yrs ago...
and the newer heads dont have the ports of the old 351W.

See Post #12 ..... 4 lines is the P heads.... therefore 3 lines are the plain gt40.
They have hard seats but around 63 cc chambers. 302 heads with the fat spark plugs are smaller.
302 heads with the 5.0 type rocker arms starting in 74 had small spark plugs and big chambers. The same head was used on the 351W.

What HP engine was your 302 when new?
What RPMs range does the Crane cam pull in? 1000 - 5000? Up to 5500? Up to 6000? Up to 6500? Is it a solid or hydraulic cam?
GT40/GT40P heads are better than other 1970's heads... don't know if better than 1960's heads... there are instructions online on how to distinguish GT40 from GT40P heads...

97 was a split year. Lates had P heads with 4 bars lines cast on the end. Need different headers to clear plugs.
Big combustion chambers. @62-65 cc nominal. Compression?
The 68 302 4bbl had 54cc heads but a slightly dished piston. There 3 different dishes through the years and heads up to 65 cc on the smoggers.
Assuming stock lift cams, Flattops with valve reliefs with stock valves will clear ok unless you mill the heads, then be sure to clay them.
Milling the heads' deck requires also milling the head's intake surface, or .... you can ruin the intake manifold by milling it and making it unuseable on any other engine.
Sometimes you can squeeze by using extra thin intake gaskets to make up the distance shrinkage of not milling the head intake surface.
Stock Mountaineer rockers work fine with stock 302 pushrods... All this assuming youre sticking to a low lift - .478 cam.
You might expect 25 hp increase minus any compression loss.

On any of my engine builds i use the clay. never mind do not argue with the old guy just do it. Only takes one blown motor to cure you...
A fellow can get by if he is just doing a valve job on a stock motor..

Putting this together and experiencing some piston to valve contact, broken valve train components due to coil bind or poor rocker geometry makes degreeing the cam seem like a function that cannot be excluded.
