Finished the motor and now I need to build a hot rod to put it in. Had a 51 Ford truck cab that looked like a good candidate.

 Too much glass in a Ford truck so I chopped it...

 Pulled an S10 frame out of my personal junk yard and dropped the motor in it and set the cab on it...

 Doin a back half to fit the 16 x33 Goodyears I have for it, basic ladder bars, coilovers and 9 inch rear.


More later as I progress!!

 Thanks JM..I've done this a time or two in the past, never pretty but I'm more concerned with function than beauty. Hope I can make this one work well. Wish me luck :Smiley

Few pictures of the work I did this week. The anle frame work is for a flat style bed, you can see the fuel cell mt and battery box.

  Roll bar finished and framed up floor and got some sheet metal installed. The strut bars thru the floor are welded on top of the x member that the front of the ladder bars mt to.

 Fabbed a on piece firewall and dash out of aluminum but need to fab brake pedal and master cylinder mt to finish the floor then thro some paint on all that bare metal.


Should get that done next week then start puting it all together!

All the serious fabrication work is done and I'm puttin it back together. Thought I'd post some pictures from today. Wife stained some 2 x 4s for the bed, got the farm truck look.

 Hole in the back is the battery box. Made a plywood cover for it and looked like a good place for a Cadillac emblem.

 Sheet metal installed and seat bolted in. I figure this truck will weigh about 3000 lbs. Didn't really try to build it lite even tho ther is some aluminum.

What a neat hot rod!!
Doing the work yourself just makes a person feel like they've done something. Nothing against the bazillion $$$ cars but I'd drive this thing a bunch before one of the store bought trailer queens.
Again - nice job

Thanks Marty...I like it too!! I don't have the patience or the skills to build a show car and don't want to. I enjoy the build and once it's running I don't worry about it getting dirty or scratched Grin

Been a couple weeks but I've got enough done to fire it up. Built headers this week and finished wireing and plumbing so it was time to put oil and fuel in and try to start it up. Had a bit of a problem with the fuel pump, Holley copy called procomp, made noise but wouldn't pump. Fixed that and primed the oil pump, dropped the dizzy in and cranked it and she fired up. Had 40 lbs oil pressure at 2300 rpm and let it run foe 6 minutes til temp went over 220 so slowed it to idle where oil pressure drops to 25. I'm used to Chevys with high pressure pumps but I'm thinkin the stock relief spring is why only 40 lbs, I don't think this is a problem since motor probably won't see more than 5000 rpm. What do you think?

 Hope this radiator and fan set up will be enough to keep it cool at least at the track. I need to change the upper hose cuz it is too short and has a slite kink out of the top outlet.
 By the way I'll be changing the plug wires as well, had this set with the 90* ends on the shelf so used them for now.



 Heard some lifter rattle on the right bank  at 2300 but nothing at idle?? Ideas?

What oil?
40PSI sounds a bit low, especially on a cold engine unless you have thin oil.

Is it a new pump? Old pump rebuilt? Iron or aluminum?



As to the lifter, what rocker arms?
Assuming hydraulic lifters, did you check the lifter preload on all 16 lifters?

St Dog..Oil is rotella 15-40, aluminum pump is used in very good condition just cleaned everyting real good including relief, just reassembled it. 40 lbs pressure cold and hot during cam breakin, pressure didn't drop until I slowed to idle to around 800 rpm, pressure dropped to 25 and steady.
 I'm using potters shaft rockers with hydraulic chevy lifters, 10.100 3/8 push rods. When I assembled valve train I brought piston to TDC compression stroke, set each rocker to 0 lash plus 1/2 turn preload. Did each cylinder the same.
 After the motor cooled I look at the valve train on each side to be sure there is no interference like push rods hitting the guide hole ect. I see nothing but will check lash [preload] when I get some time later this week. What do you think?

1/2 a turn of preload may not be enough. Not sure as I've never used adjustable rockers.

As to the pump and oil pressure, sound like you have an old spring that has weakened with age.
I think rebuild kit from Melling (only supplier I know of) includes a new spring, plunger, gears, and a gasket.

Fuzz,

Looks good!


Both of my engines had apx 60 cold above idle, 50-55 hot revved, 20-25 hot at idle [loose clearances].

How thick is the pump gasket? Too thick = too big end clearance on gears = low pressure.

Assuming that you didn't buy the shaft rockers lately, the p-rods may be contacting the *rocker* body under the screw area. Common problem that has been addresssed lately.
