Radiator and Engine Offset

I acquired my 68 recently and found that it vapor locked easily, in fact it did it on the way home the first day. Anyway, we rerouted the fuel line and it helped. Now I have another problem, the fan does not reach the shroud, even with a 2 3/4 in. spacer. I bought a new flex fan and 2 3/4 in. spacer, thinking it would be better than the clutch fan in cooling, but either way it doesn't reach it. This weekend I drained the radiator and attempted to push it back toward the motor and after cutting a 3.5 in. spacer to keep the radiator in place (and it looks dumb!), it finally goes into the shroud. Then while looking at it further I noticed the radiator has no mounting brackets, it was just rigged to press against the radiator mount (with these custom brackets) and then in looking at the radiator mount it looks like it doesn't belong either (no holes for mounting to). I'll take pics and upload tomorrow morning so you can see.

My questions are, 1) why on earth is the engine so far back and why is it offset? It seems to sit further to the passenger side than in the middle, causing the fan to be offset and therefore I can't sit a shroud directly into the middle of the radiator...2) Should I invest in a Radiator mount and radiator to get it all fitting better? I will still have that huge gap between the fan and the radiator so why would I spend all that money? 3) Should I just get an electric fan on the radiator and leave the flex fan to blow into the engine bay helping the vapor locking issue even more?

If I go with 3, do you have any recommendations? I live in South Denver, CO and mostly do driving under 45 mph so maybe electric is the way to go?

Re: Radiator and Engine Offset

The BBC was off set to the passenger side because the engine was too big to fit in the engine bay centered. The exhaust manifolds would hit the steering gear box if centered.

You didn't mention engine size, or whether you have a long or short water pump, or anything else that could help diagnose the problem you have. To further complicate the issue if you have a non-stock part (custom brackets) then no one can answer the question because no one can see what you are dealing with over the internet (the ole how many fingers am I holding up?).

We can answer questions that we have dealt with concerning stock parts because most have a Chevy that uses the same parts as most (but not all ) Chevy's. When you go off the deep end with recycled race cars or custom fabricated cars our experience pool dries up, because they are usually pretty unique.

Re: Radiator and Engine Offset

I can tell you that on my stock 67 L35's the fan blade only goes into the shroud about 1/2 the curved blade thickness. It may not look sufficient but you can feel a very health pull if air when you place your hands in front of the radiator at idle.

Re: Radiator and Engine Offset

this is my 68. it is a SB on BB frame mounts, BB transmission cross member and BB fan shroud
I had to alter the shroud and use a 2" spacer on the derale flex fan to get the fan blades half in the shroud
the 3 core radiator bolts directly to the radiator support

Re: Radiator and Engine Offset

Change the frame stands, Z-bar, transmission cross-member over to the correct SBC parts, or yank the Whimpy 383 for an Edelbrock crate 555 Pat Musi BBC (that puts out Bluto sized 697 HP & 643 TQ), and feed it spinach. Your problem will go away either way.

A BBC is two inches longer and nearly three inches wider than a SBC (it's also over two inches taller depending upon choice of intake than the SBC). Which is why unlike all of the other GM motors a big displacement engine is actually physically bigger; unlike Pontiac and Buick that have a 455 that can not be told apart from a 350 just by looking at it at a car show.

Yep, sorry for the lack of information. I am just getting into the "car thing" and learning a lot. It's a 350 from the looks of it. I don't know how to tell if it's a long or short pump, I will have to look that up and update this thread. Sadly I have no idea what they did on my car, I'm just having to feel it out and upload pics to see if anyone can help me.

Where did you get that offset fan shroud? How do you measure to get one to fit?

At this point I'm looking at the Flex-a-lite 52187, which is a new aluminum radiator and an electric fan. From the looks of it, 3300 CFM will cool a 350 just fine. Why not start fresh with something that fits my car? Only problem is will it attach to the radiator mount...I'm not sure. I guess I can drill holes and force it until I can afford to buy a radiator mount. Anyone think I should spend the money on a new one?

Thought it was directed at the original poster, sorry if I got you by mistake. Not casting dispersions: Wimpy is part of my Pat Musi (aka Popeye) engine reference. Though depending upon your age you may not know the names of the main characters such as Wimpy, Bluto, Olive Oil, Sweet Pea, etc. The Popeye cartoons have been off the air for decades.

1/2 is what it should be.
