Oil pumps come both sizes. Get the correct tube and stake it or tack weld it, make sure the tube, oil pump, pickup and pan are compatable. If you got the billet cam with pressed on iron gear I recommended your stock Dist gear will be fine. You will need a roller tipped, composite or bronze tipped fuel pump pushrod.
with tack welding or they have a bracket that holds the pick up on! I lost a pick up on my 427BB after an accident and didn't notice for awhile because at idle the oil level was high enough for the pump to make pressure but as soon as I started driving it would fluctuate big time!
Spoke with comp cams. They advised use of a melonized dist. gear. Spoke with Performance Distributors. They checked the # on my dist. It has a standard gear, so I ordered a melonized gear from them.
Also,
Checked on Summit. Yes, there are different sized inlets on the Melling pumps. Wouldn't have known for sure without the pickup on hand. Summit lists Melling p/n 10553. It is a high pressure pump that comes with an extra spring to change it back to standard pressure. It also has the 5/8" inlet. Does this sound acceptable? Surely it can't be too difficult to change out that spring...

AFAIK, a composite dist gear will work with any cam material. I will be using a composite lightweight fuel pump pushrod also which will work with any cam material, again, according to the cam makers that sell them.

You must have not gotten the pressed on cam gear. Then you need the melonized dist gear. That Melling 10553 will be fine. I think the relief spring is held in by a threaded plug. That said I would probably leave it as high pressure. All it will do is allow higher pressure before bypassing the oil filter. It will not increase pressure at idle or even cruise. Just higher rpm
I just had a customer with a Camaro have an issue with Hamburger pan. Hamburg does not make a pickup for an HV pump. They don't make a bolt on style pickup either.
HV pumps are .250" longer than std volume. Using a std volume pickup on an HV pump puts the screen on the bottom of the pan and it will cavitate. B&B makes pickups for 3/4" and the bolt on style.

Block and rotating assy are at the machine shop. They should be done with it some time next week. My bud will be back this way next weekend, and we will start assembly. Still a few parts to order, nothing that will hang us up immediately. Still looking for some suggestions on clutch, etc.
Question:
The Air Gap intake has two 1/2" NPT holes in the back, for a coolant crossover?
Should I plug it or plumb it?
Please post thoughts, pro and con...

I plugged mine and figured that if I ran into heating issues that I would plumb them. Other members have ran the plumbing from the front to back in order to circulate. I'm sure that some one will comment on why I did it wrong.
Made some hay today.
First off, these are a real pain...
Assembling pistons
Getting set to check the crank
Filing rings to spec
Pistons assembled, ready for install
Block slugged
From the bottom:
All mains were clearanced, as well as the con rods. Clearances were across the board
.0175. Most freeze plugs, oil filter adapter installed.
63mako, you da man!! These parts are just fabulous. The consistency throughout is unreal. All the pistons weighed the same, as well as the con rods. It was a fun and educational day for me.

Didn't get a whole lot done yesterday. Have some fitment issues with the cam and timing gear. The bolt holes don't line up. Also, same issue with the cam retainer plate, bolt holes not lining up. I'm going to call Comp. this AM for suggestions on these small hitches. We did do a little though...
Head studs installed, heads dropped on:
Note my bud's sicka$$ '68 F-body.
Also installed oil pump and pickup. Hopefully I can resolve this stuff and we can get back at it this upcoming weekend. If not, it'll be two.
Thanks for y'alls replies, and as always, your comments/suggestions are valued!

63mako,
Yes, the Compstar con rods are brilliant. You start checking/weighing this stuff, and about halfway through it, and each time it's coming up the same weight/clearance you're like "Need I continue??" It probably would have been OK to stop, but we didn't...
Carter
Comp Cams is sending a new timing set and cam retainer plate. The cam is a late-model, and the bolt holes are different. Also, the SHP block uses a different cam retainer.
Squared away.
