Building a inexpensive rat rod out of a 67 econoline pickup using up some old parts I have. Truck was 2400lbs from the factory. I'm installing a 351 clevor and moved it back 14" with a top loader. Engine = 4.00 scat crank, 6.200 rods with dss pistons, should be about 10.6 to 1. Factory Cleveland quench heads with a little bowl intake side and as much smoothing i could to straighten  on the exhaust. 2.190/1.71 valves, Wieand boss tunnel ram using PMS adaptors, 2 650 dp brawler carbs, I have many different gear sets up to 5.14 for the 9" and looking at a Crane# F-248-3334-2-8 cam= .533in .555ex but will be running 1.8 rockers to make it .599in and 624ex. Adv duration 310in 320ex, @.050 .248in .258ex on a 108 lc timing events are open 21*in and 62*ex close is 47*in and 16*ex. I used to run this cam in a bogus boss 302 in the late seventies and it was ok. Really just looking for something on a shelf as it's probably not worth bothering people like Brent Lykins or anybody.

It's not hard to straighten it yourself. I made a 9"x48" straight edge out of 1/8 steel one side has the center housing area cut out the other is straight for holding against the bolt surface. There is how to youtube videos on this. Yes a simple straight edge will give you thousands of trouble free miles. Only need the bar thru center and bushings if your building a housing from scratch. All housing from back in the day are bent especially trucks, and I've seen them go thousands of miles being bent. Roads were a lot worse back then. Mike

In 1983 at 12am, leaving a second job at Randy's Ford Specialties working for boss 302 parts, i'm jumping on 270 heading home and a 260Z racing up on my mustang and thought he was going to get around me so i mashed it. Was pulling away from him and at about 90mph she started slowing down. No real commotion just dying off gently. By the time i made it to the next exit I was at 15mph begging to make it up the ramp. Pulled into the lights at a self serve station and had hood up checking everything, got fuel, pulled the cap and rotor checking points. All good there, put rotor back on and turned it 90 deg??? Pulled the dizzy and sure enough I sheared the roll pin and gear was slowly spinning on the shaft taking it out of time. Dug around in the bottom of the toolbox I found a nail that was a near perfect fit. Stuck it in and bent it around, pulled number 1 and stabbed it, tune by ear and ran another 10 miles down the hwy to home. Pulled in at 2am and back out the door at 6am again for the real job at supreme grinding and was feeling rough. Fun times had by all.   Mike
                                                                                                                                                     

Guess I could have gave more detail.
You need to be pushing mid to upper hundreds in microns. Pick up screens are large debris filter screens only. Screw on filters are like 20 microns I think. 500 micron is 0.0196 in thousands. I talk to them and think I got around 750 screen or so. I wanted it to flow and low drag on components. To small is hard on dizzy gears and roll pins. HAHA I personally was not worried about being to big in my drag car, if the engine started to come apart there was bigger problems and the pick up screen was useless anyway. I always cut my wix filters open to see bearing life back then. Mike

Love the idea of the more stock appearing tunnel port with new technology, with a slightly raised exhaust port (exhaust is a big killer in fe's) would open more doors for show/street/strip people. I would be up for that.

I also believe the cam is not a good match and needing a little less duration @ .050 with more split keeping more air/fuel mix in the cylinder to make power. Flow should not be a problem at all. 13-1 static compression and thinking the dynamic compression is way lower due to mix bleeding back out valves. Yes it is a guess with out knowing the actual degreed timing events but can explain why it liked the new headers so much by them helping to get air/fuel back in the cylinder. A full 10 hp difference from your regular dyno headers that your 585ci drag week engine ran on? Your work is outstanding!!! One sure fire way to know is to pull a jon kaase if you can find a finger to sacrifice. LOL I always laugh at that cuz it looks like something in a cartoon but proves a good point.

Ya really nice stuff there that I also kinda hate to see. If you really think about it we are a dying bred. My grandson would like to buy something to have a project to learn, gain experience's from and enjoy just like we did. Now people think there junk is priceless. Teens don't make that much money. It's 10k for something decent enough to even start with then a full restoration. Go by your high school and look at the cars, I remember primmer and mags. LOL
Not a big fan of whats happening in the auto world today. Remember the days of racing, drag, stock car? They were real cars and people we celebrate about because it's all corporations now and little to over the top crazy for me, and getting worse. What will we see in 10 more years? They are already driving for us now. Oops turn into a rant, just saying.
