    Sandin A/C and compact P/S pump brackets

    I'm liking the set up but I have one question do you think it would all fit with the battery in the stock location or does the battery need to be moved to the trunk

    Sandin A/C and compact P/S pump brackets

    It’s probably the same kit. I’m running p/s but you can’t see it in those pictures and the water pump outlet is on the other side for 69 and earlier. I need something that would work one the six pack intake. But it all fits. Now We are going to try to but it on a Str-12 intake with fuel...

    Reusing rods

    If I change any internal components except rod bolts, I re-balance the assembly. If it's internal or external balance I send everything that spins to the balance shop. I do this for two reasons. One is I don't want to make a second trip and two overtime a balancer can be out of balance itself...

    Slightly disappointed in performance

    My 2 cent the cam is on the small size and the dual plane intake may not be helping on top end at all. Like other have said what was the engine built for and what numbers do you have. We are just guessing without knowing what is hurting is it 60 foot or top end. The really answer is in those...

    Issues timing a new rebuilt 408

    Are you using a vacuum advance and if so is it on ported or manifold vacuum? I would think you need to limit mechanical advance to about 30 degrees and hook the vacuum advance to manifold vacuum and have it limited to about 24-26 degrees. So at start up and idle you have the vacuum advance pull...

    Replacing main bearings without removing the crank

    I do the same thing put I use half of a large cotter pin. cut it at the top and bend it over 90 degrees. put it in the oil hole and away you go. But great video if you need to replace mains in the frame it's a great little trick

    408 still overheating :/

    This may or may not help but we're is the timing set. Not enough timing or having the timing locked out can cause the engine to run hotter than it should. Depending on the quality of your fuel you may need more timing not less and you may want to run a vacuum advance to help with timing at...

    ? Has anyone used amc lifters push rod oiling ect .

    I use AMC Lifters in my Stage V Hemi conversion without any problems at all. The conversion needs the rockers oiled through the push rods because there is not oil hole from the block to the head to feed the rockers and there are two drain back tubes in the back of the engine for oil return to...

    Cracked valve guide, any advice?

    If that head came into my machine shop I would replace the guide and make just the installed height is correct. With that being said you still need to spend a little time figuring out why was it damaged. Was it damaged when it was installed or was the installed height wrong and maybe the...

    If you bought a cast 4" crankshaft

    I check the balance on any rotating assembly that is not stock, most are good but every now and then you get one that is off. I have a SB Chevy with a Scat kit out being balanced now the customer bought the kit and it was suppost to be balanced but vibrated so bad it broke the bolts for the...

    How to put together cut to length pushrods

    I use the Comp set up to ream the end of the push rod and square of the push rod tube. I always cut the tube .010-.015 long and cut it down to size with the reamer. Also if you don't have a way to hold the push rod tube straight and keep it lined up with the cup end it will bend really fast and...

    Cylinder boring question

    Put a sleeve in it. It will last the life of the block. I use sleeves to repair race blocks when they crack and they work just fine for and its cheaper than starting over with a new block.

    avoiding hot tank fees

    I charge a flat fee to remove cam bearings, freeze plugs and hot tank a block. I'm not going to put someone's grease covered block in my boring machine and leave lots of metal shaving stuck in the grease so some body can tell everyone what a bad job I did. When you get your block back from any...

    Pistons in hand when boring?

    I want them in hand, measure them all then bore to 0.002 and hone to each piston that way the pistons are a good fit and the rings get filed to each bore as well makes for a nicer job and doesn't take much more time. Just my way

    Magna-fluxing found a Crack in one of the heads

    When I pressure test a cylinder head. I use a plate that covers the gasket surface and plates that block the ports for the coolant that goes into the intake, then just add 40psi of shop air and apply a soapy mix and look for bubbles. cracks between the intake and exhaust seats don't always leak...

    question about valve stem seals

    I would go with the Felpro set for the street and the positive seals if it's just race. Sometimes positive seals on the street don't let enough oil on the exhaust valve, valve stems this can lead to valve guide wear or a stuck valve depending on the valve to stem clearance. Race engine run for a...

    Eagle 3.58" cast crank, who's broke 'em ?

    I have heard of cast cranks breaking when people run a two step and stay up on it for a long time or run a high rpm leave chip which shocks the crank real hard. Just my 2 cents but I have never broken one myself.

    sunk valves, stem height problem

    I think you need to get the valves to the correct installed height and spring pressure you need for the cam you are running then if the tip of the valve is to high and the rocker arms don't touch the valve stem in the correct location you can shim the rocker shafts up to move the rocker arm to...

    eddy heads to low cc for me??

    Without all the exact numbers it is going to be hard to tell but one good thing is the aluminum cylinder heads will absorb more head and you can run a little higher compression without any problems. Just make sure to check piston to valve clearance by using and old head gasket and some modeling...

    oil pressure and adjustable hydraulic valve adjustment

    Let me understand one thing is the oil pressure numbers you gave are at an idle 12 psi and now it's 55 psi if so 55 psi is way to high. Most oil pressure is checked at 2000 rpms. If you have 55 psi at an idle and the engine hits 5000 rpms and oil pressure increases you could have well over 100...
