test fitting a intake with the intake to head gaskets in place,what is the normal gap at the front and china walls.my cork front gasket slips in and out easily with slack,is this normal or should the gap be smaller

My uncle has a 390 that he had freshened up,new rings,gaskets,etc.it seems to run ok but after a few days he has to add oil and coolant.its not mixing them,its just using.

does it change the lift of a cam when you go up on the rocker ratios,if so how much?

i have a good set of cj heads,pi intake that i would trade for a good big shaft toploader for my 66 fe comet.the heads were freshened up last year,ran about 1000 miles and i switched to bbm heads i got for xmas.both the intake and heads are good to go.

what would be the perfect oil pressure for a street driven fe.cold startup,hot startup,hot under load? not too high,not too low,just rite

i have a friend that lives across the hill from me.he has a long gravel driveway.every time i go up his road i look up on the bank in the weeds because there is a oil pan sticking up.i have been wondering for years what this engine was,so today i asked my friend if i could climb that bank and see what that engine is sticking out of the weeds upside down.he said go right ahead,that thing has been there since i was a boy.i climbed up there and pulled some of the weeds back till i could see better.i noticed it looked like a fe right away.the numbers on the block said c3 something,i assumed it was a 63 390.the oil pan has pin holes all in it,and it looks thin.the heads and intake are under ground.i told my buddy i would give him 20 dollars if he would let me roll it down the hill into my truck bed.he gave it to me and said if anything is left of it i hope you can use it.i have not picked it up yet,but wonder if there is anything still usable on it?its been upside down in the weather for at least 40 years

i hooked a vac guage to my carb today.what are some reasons for low vac at idle.i could not get it above 6

 i have a 1 inch carb spacer on my 428 right now.bbm heads,rpm intake,msd pro billit,..245 comp hyd cam,850dp,speed pro 10.7 pistons,arp.my question is should i have a noticeable amount more low end torque without the spacer?
