Depends on the set up. My blue 70 Challenger sits lower than all of my other cars and I have the most clearance on this car with headers, an 11 quart oil system, deep trans pan and 3-1/2" exhaust using a tubular K frame with coil overs.
I run 235/60/15's on the front with 5 different sets of wheels and tires with all stock front suspension and ride height with no rubbing issues. The 2 other sets are currently on other cars.
The 2K is excellent to use when you don't have all of the equipment like a compressor a paint gun and all of the supplies like sealer, epoxy primer or self etching primer, paint and clear along with lacquer thinner and everything for clean up.
Good to know I suppose. Both my 70 R/T S.E. Challenger and my 70 Charger R/T S.E. have power windows and I can honestly say that I have never had to look for either relay as both cars power windows have always functioned just fine.
This is my self etching primer and hemi orange Duplicolor engine enamel process that is about 6 or 7 years old now with thousands of miles and many passes.still holding up well.
Without you knowing all of the specs of your engine it is just a guessing game for us. If the so called rebuild is just a gasket job and repaint on a later smog 440, your horsepower is way less than the 385 you think with only 7 or 8:1 compression. Sure, a 3000-3400ish converter and 4:10 gears...
Hmm, I have always just dumped them in a 5 gallon bucket with some cleaning solution for a couple of days and they come out looking like new. Then throw them out in the sun to dry.
Nothing wrong with Comp. Yes, you hear some horror stories once in a while. You hear those horror stories about everyone's product eventually if you build enough engines. We build a couple hundred engines every year. Most with Comp Cams camshafts with no issues.
I have done it on a couple of my cars over the years. It was all custom made by me. Nothing of a kit except a factory 440 sixpack base from an A12 Bee or Bird.
Are you sure it is lifters and not the rockers clattering? Did you re-install the rocker shafts correctly on correct side from front to back with the oiling holes facing downward towards the #4 cam journal.
