Title: Finally got my motor back
Post by: tparker on April 29, 2021, 03:45:19 PM
Yay, I got my motor back finally. The wait was crazy. I dropped it off back in September of 2020 or so. They were backed up, slower than normal, and parts are getting harder to get apparently. 340 stroked to 416 :) Scat crank and Hughes cam. Hopefully paint it next weekend and start assembly and then shover 'er in.

My 440 has been in our local shop for just a few months shy of 2 years and the lower assembly is just now done. Your guy is FAST!!! Lol.

^^^ NICE! Going to hit that thing with some blue before you stab it in the engine compartment right? What are the specs on the cam? Interested as I note the stock rockers in place.

Orange actually. I picked up a cam from Hughes Engines
http://www.hughesengines.com/Index/products.php?browse=search&search=SEH2832AL-10&partid=30242

I might redo, or possibly replace, the heads later if need be. I'm doing it on a budget and what I have should be fine for now. It isn't gonna be a monster built should have a lot of fun packed in.

Congrats; looks good  :bigthumb:

Took about six months to get my block checked out; bored; cam bushings installed; rods reworked and bushed; and crank ground.  The crank grinding was the major holdup as the grinder quite taking in new work and they had to find another shop that was also backed up.

Here's another vote for the orange! That's what colour my 408 will be if I EVER get the car painted. LOL Good luck with it and I'm sure you'll be happy.  :bigthumb:

What CAM did you get ?   What Intake manifold and carb ?

Looks awesome.  Make sure you save some money for a second set of tires. :stayinlane:

I got a Hughes engine cam. The link is above for the specs if you're interested. I have an old Edlebrock manifold I've had on it since about 1990. I might upgrade it later since there has been some advances since then. I picked up a 750 Edlebrock carb. I also have a couple carter AVS. Not sure what I will end up running. I mainly picked up the Edlebrock because it was running and I rebuilt the carter. I don't want to mess with anything else while I try to start it for break in, so I went with a carb that is known to work.  :)

That Hughes cam has .530 int and .536 exh. lobe lift with 110 sep... should be fairly choppy. I see that you are using the 1.5 stock stamped rockers. Any concern using the stock pieces with that much cam? I just received an email my Promaxx heads are being delivered early this weekend. I've been shopping rockers. My cam has .454/.454 @ 110. Thinking of using 1.6 ratio rollers to get that bumped to .484/.484 as the new heads should flow a better than the stock and the springs are supposedly good up to .600.  I've heard the stock stamped rockers are good up to about .500 lobe lift. And those springs will need to be fairly stout. Hate to think of one of those pushrods punching through the rocker.

On the intake side.. which Edelbrock do you have? Older RPM maybe? I currently have a Weiand Action Plus sitting on top. The previous owner gave me a Edelbrock Air Gap.. chrome unit he kinda made a mess of around the thermostat.. has black RTV or some other sealant caked on it. Most of that is hidden behind my AC compressor and I hear the Air gap is the dual plane of choice nowadays. Thinking of tossing it on with the new heads. 

On the carb.. I went with the 625 Holley Demon vac sec. & could not be happier. Is your ride manual or auto?

Maybe it just me but Since the goal should be on a new engine to not get any dirt etc... on the inside,... no valve covers, no timing cover, open valley, open intake ports and a chain laying in the valley. Anything that has oil/lubricant on it will just be a dirt magnet. and is just asking for dirt/debris getting inside when you get it assembled oiled up and then started. At least blow it off and bag it. But...not mine.

Make sure you put some zinc additive in that baby before you fire it up :)

That's a pretty big cam, it should put out some power. Love the small block stroker.

This is what I used on my 416 for break in additive.

@Scooter (https://forum.e-bodies.org/mlist/scooter_5461) The builder seemed to think it should be ok. I worked with a guy at Hughes engines and they recommended the cam, so I hope it should be good. They have a slightly different philosophy about cams and lift. Not sure if that applies here though. They did highly recommend bigger springs which I got and put on. Had to do a bit of machining to get them in correctly apparently.

I think the Manifold is an old RPM. No real markings on it other than Edlebrock and a part number on the bottom. I got it around 1990. The tranny is a 727 torqueflight.

Yeah agreed. I took the bag off for the pic. DON'T want any dirt inside. It was uncovered for less than a minute. The dust in my area is horrible. And it is a sandy type. But no you have me thinking about my strategy for painting it this weekend to minimize any exposure to dust.

Oh yeah. The instructions are VERY clear about this as was the builder. I will check this out. My builder recommended a product that I forgot the name of, but was the same that several people here recommended.

Not great photos, but got a few with paint from Frank Baldason, It came out OK. A couple runs on the valve cover unfortunately. I'll begin to put it back together and in the car after a couple busy weekends pass. Maybe firing her up before July?
