Actually, all of their products in general.

I know they sometimes get a bad rap so I wanted to discuss my experiences.

Had their water pump and housing on the 906 headed 440 along with their upper pully, alternator bracket and oil pan/pickup. Everything fit perfectly and worked perfectly the first time with NO modifications and NO leaks. The engine stays at 190-195 degrees even after beating the snot out of it!

I did the Stealth head swap this weekend and it was VERY easy. NO pushrod clearance issues etc. like others have mentioned. These castings are less than a year old, though, so that may explain some of it. Very nice castings. We had a shop look them over and install new valve locks and springs just because.

I do plan on beating/driving this thing all over this summer to events and the dragstrip so if I have ANY problems I'll post them here.

Overall I'm impressed with their quality and fit/finish. I'm just happy to have a place that has good quality stuff that gets parts sent out in a timely manner! Makes the hobby much more enjoyable.

This winter I plan on slipping a new 512" stroker kit in the shortblock.

I have not had any problems with any of the parts I have got from them.

I bought a 512" stroker kit from them recently and had my machine shop check it out. They said there was nothing wrong with any of the parts and that the balance job was not absolutely perfect but not worth redoing. Everything else I got from them including a passenger drop water pump looks good. I just need to start bolting things together.

Yup - that's 'Source. Great Value . Not necesarilly the best quality as delivered.


Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I'm running Source stealth heads, Source head bolts, Source water pump & housing. All items bolted right on and have worked without issue through plenty of abuse. I'm thankful for 440-source.

My junk 498 440source ran 8.60's -8.90's for 276 passes in my Daytona. It is still going strong on the street for a friend of mine. If I ever get a chance to throw together their 512 assembly I have sitting here I can't wait to see what it will do

yep their stuff is ok by me , 2 sets of heads , waterpump and housing.
sometimes I think people are missing what they offer , stock and mild performance . Not all out race . Their price reflects this .
if I get to a stroker it will most likely be theirs .

So, what does your seat-of-the-pants dyno tell you after swapping heads?

Wasn't able to really get on it hard. Took it around the block and it was getting dark. The couple of blips I did get in, though, felt impressive!

Easy on the 'government work' comment Brad. I was a machine tool rebuilder for almost 27 years and everything we did was spot on and better than most 'outside' jobbers. We didn't kill ourselves but we weren't slackers either and we did earn our keep until the POS politicians killed our DOD jobs in the 90s.

I'm happy with mine too.
Dan at Performance Only (RIP) told me he was very impressed with their quality while doing my build.
Miss you Dan .

I use their 440Source 4.15 stoker kit in my 440 and its been working good for about 4 years. All the parts were decent as I only did some minor touch up on some and just had to fit the pistons pins which were a tad tight. I am very pleased with it. Its nice to see people post their positive results with the 440Source parts since some of the unhappy ones post about them. Ron

The only way a machine shop will know if the crank is balanced correctly is to set everything up in the balancer and give it a spin (that is the hard, time consuming part of a balance job, drilling a tad more or a couple spot welds takes very little time), if your machine shop did all that and could not spend a few minutes more to correct the balance issue I would be looking for a new machine shop. I had a used rotating assembly checked to see if it was internal or external balance (and done correctly the first time), the guy I bought it from was not sure, they knocked $10 off a normal balance job and said it was because they still had to do the same set up and checking everything. Am I crazy or missing something?

Some shops will NEVER say another shop did a good job.

Is this with 3/8" pushrods? Did you use the same length as you used with your 906 heads?

Stock pushrods.

Yes, all the rocker gear/pushrods were the same as what I was using with the 906's.

I plan on upgrading to adjustable rockers (have some Crane iron rockers) and changing pushrods when I do the bottom end and install a solid lifter cam.
