440 Tear down

440 Tear down
Gang the tear down is complete and i just dropped all parts off at the machine shop to be tested and cleaned. I will see what is reuseable and what work needs to be done. Not bad for first tear down, I broke 1 water pump bolt and a piston, other than that all went well. I will keep the pics coming for the rebuild and will have many questions in what to use.

I got word back from my engine builder today, he said that metal parts are all good block is solid rods good heads are good. Cylinders bored 30 over, because I used the ridge reamer he may need to take it to 40 over. Lesson learned when dealing with ridge rimmer. We will sit down next week to discuss replacement parts, I will have a lot of questions concerning parts. What I am going with right now is easy replacement parts cast pistons to start with.

Thanks TVLynn, I got another call and he was able to go .30 over, Friday we will sit down with a build plan. My goal is to have around 9.5:1 CR with around 400hp. I want to reuse the stock heads and not sure how much work will need to be done with that. Any ideals on what size cam to run with those style pistons?

update to the rebuild. Bored the 440 .30 over going with TRW Forged pistons and performance rings. Comp Cam- Xtreme Energy™ Hydraulic Flat Tappet Camshaft 21-223-4- good for street machine with a slight rough idle and power 1600-5800 rpm range. Hydralic lifters, double roller timing chain. New ARP bolts in the connecting rod and main bearing caps. Using a Hemi oil pan with sump pump, so that I get better flow over the 440 stock with the use of high voume oil pump. All this with the goal of 9.5 CR and 400 hp. What are your thoughts?

It's Eric and your using a HV pump. You might as well suck a 1/2" tube instead of 3/8" tube. I just switched to external pumping with a 7/8" suction line.

hey joe do you know what year that block is I have a similar block with a whole in the front of it and I want to see if it was casted that way or if mine is shot it looks similar to yours but with small differences and do you know what your block came out of and if you know the numbers off it sorry if I'm asking a lot I just haven't been able to find any info on my block

I wouldn't drill the block to 1/2 npt for the pickup rather leave it alone and use an adapter for 3/8 to 1/2 pickup tube. Unless you run a 7 quart pan there is the possibility that you will put oil up faster than it can drain back especially with stock heads. If you really want to improve oiling there are certain galleys on the block that should be reamed to a larger size. This info is all over the web but I've posted a link below. Remember that oiling is the life blood of an engine and this mod is highly recommended by most engine builders. Also, I wouldn't use Comp anything because most of it's offshore and R&D and Quality Control on their stuff seems to be more directed to the shareholders than the end user these days. Lunati, yes, Comp, no.
