Project HEMI 55

The link does show that the bore spacing is the same.

The difference must be in the front end of the engine, if it's accurate. Timing cover, water pump, etc.

I suspect it's pretty general but it is used by NHRA for tech inspection or at least it alludes to that. I'm only the messenger however always thought the same Rick. I did some searches but this, for now is all I could find.

Here's something Steve sent me but I don't know how accurate it is. He has an electric water pump on the engine that extends way forward but he says it's not significantly longer than a stock mechanical pump.

Engine	Displacement	A length	B length	C height	D height	E width	DIST	SUMP	STARTER	OIL FILTER	WEIGHT
Mopar	273/360	29.50	29.50	23.50	31.00	25.00	rear	front	left	right rear	525/560
Mopar V10	488/505	36.88	36.88	23.50	x	25.00	x	front	left	right rear	716/816
Mopar	350/440	29.00	30.00	24.00	30.50	29.50	front	center	left	left front	620/670
Mopar	331/392 Hemi	32.00	31.00	24.00	31.00	29.00	rear	center	left	right rear	729/745
Mopar	Late Hemi	32.00	32.00	24.00	32.00	29.00	front	center	left	left front	765

A - Length from rear of intake manifold to water pump pulley
B - Length from rear mounting surface to water pump pulley
C - Height from bottom of sump to highest point of intake manifold
D - Height from bottom of sump to top of carburetor
E - Width outside of valve cover to outside of valve cover

That data is at the very bottom of the link I posted. I was always of the opinion that the blocks were the same dimensionally, i.e. length but I know physically, there are other differences.

I got the body off the frame a while ago using some simple brackets I made for the rear body mounts, a spreader bar, and an engine hoist. I used a similar setup in front:

Then I pulled the engine, installed a Milodon remote oil filter adapter to eliminate the interference with the rack, rotated the rack, and repositioned the engine further forward and down as low as it will go.

Unfortunately the custom-built headers don't fit anymore, but Steve thought they were crap anyhow. The other shop hacked up a new set of headers he had and threw them in the trash, which is where these are going.

I cut out these crappy engine mounts the other shop built to get ready to build a new set. Notice the steering shaft notch doesn't even line up with the rack, and there's no way to remove the upper a-arm bolt on the driver's side.

Then I mocked up the radiator support and SPAL fans and did the final engine positioning.

After moving the engine forward as far as possible, the Gear Vendors overdrive still fits but the speedo sensor notch will have to be modified. I will also have to modify the transmission mount to lower the GV unit a little and move everything forward. We ended up gaining about 3/4". That doesn't sound like a lot, but the engine mounts had to be re-done anyhow to get the front of the engine down, which was Steve's biggest complaint.

Seems to defeat the purpose of a C4 front suspension don't you think?

55 RD, is it your intent to mess with every single post on this site? If your intent is to destroy it, then my suggestion to the owner is to do away with either the site, you or me so I don't have to witness the demise of it.

The dumbass buys a C4 frame and all he does is bash everything about it.

I'm doing what the owner wants me to do, so STFU RD. All of your ignorant posts like this will be deleted from All of MY progress threads. If you want to start threads of your own to bash what you bought, go for it.

I enjoy when you explain your work (including what you're trying to accomplish) and post pictures of each step. It helps us all visualize better, and allows others to ask questions when they see something they either suspect or are confused by. Keep it up Laszlo...the world of Tri5 builders is better off when we all use this forum to help each other get these cars built.

Thanks Paul, I don't mind questions about what I'm doing except when the questions are nothing more than thinly-veiled criticisms, insults, or snide comments just to start an argument. If someone wants to discuss the benefits or deficiencies of a C4 suspension, they can start their own thread or go post on one that already exists and not continually disrupt my build threads with OT posts or irrelevant comments.

This build has been kind of unique, that's why I've chosen to post a thread about it. There are some challenges that we don't face with other engine installations we do.

Well, just when I was getting into the design of the engine mounts for the 440, Steve contacted me and wanted to talk about something. He found an early 392 Hemi with dual quads and the price is supposedly so low he can't pass it up. I looked over pics of some of these engines and don't see any big showstopper, so now we're back to a Hemi.

I have to pull the 440 back out and put the body back on the frame to store the car for a couple weeks until he gets the engine and adapter for the 727 Torqueflyte. I have two other frames to build so I need to get working on them and will get back to the Hemi55 when I can.

go slow... it might give him time to change his mind again.. back to what's in there now...
