having half a fit with big block headers

[steverino66]

Test-fit the headers today on the 454.
Passenger side just touches the frame - no problema.
Driver's side needs another 1/2 inch to clear tower on the bottom of the #1 tube.
Don't really want to get out the big hammer - will the tubular aftermarket towers solve this problem? (current towers are small block with the hole elongated slightly to line up with the mount on the engine)
I know some of you guys have solved this problem - help will be appreciated.

Wow I'll never look at my L6 250 the same. Thats a big motor my friend.

if you want total clearance without cutting up a mount you can use these mounts. And this is my big block build thread http://67-72chevytrucks.com/vboard/s...d.php?t=259536

When I did my Burb,I used headers for the '73-'87 trucks. I trimmed the top flange of the frame rail on both sides, using a '73-'87 frame as a template. As for motor mounts I again used the '73 and newer mounts with custom built brackets. It looks like the tubular ones that Chevy Fleetside used would be the solution to that problem for you.

this must be the "to much work" you described in my thread

Fleetside -
Or anyone else - who makes the stock-looking mounts in your first pic? I've found the tubular type kit at Brothers but would rather go with the first type if possible.

Thanks for the other replies - I'm stuck with the earlier style (up to '72) headers.

Those are the same mounts you have in right now. I would have had to cut to much of the left mount away to be able to use them. I tried many mounts and the tubed ones worked the best. I just didn't like the way the 73 and up mounts looked is all but they would have worked also. I also cut my firewall so I could scoot the engine back as far as possible.

I saw some stock-looking towers advertised on Craigslist (the guy doesn't want to ship them apparently) supposedly for 60-66 - thought maybe that's what you had there; can't find any aftermarket except the tubular.
I have some 83 towers, will have to buy the other style mounts, but I'll give those a try to save the $140 for the tubular kit.
Thanks again.

No, No....I was just joking with ya. It's not really that much work IMO. It's mostly just knowing what to do.

I didn't realize that is what headers you have. In that case you should be able to just switch out your current motor mount frame brackets with some '69-'72 big block frame brackets. They are made such that they have an indent on in the top area to clear the exhaust manifolds, which should work with the headers since that is their intended application. If you need a pic let me know.

Thanks, Captainfab - I already have a set of those on the way (scored on craigslist)

http://www.summitracing.com/parts/he...olet/model/c20 They sure did go up in price. I would use the 3/4 chevelle headers. These hang down pretty low.

[ol_skool_chevy]

what year 3/4 chevelle headers would you use???

[Chevy Fleetside]

Here are some shorty headers for a 70 Chevelle. I am not 100% sure if they will work. Someone on here dose though. I would probably order one of the shorty headers. If they didn't fit I can always send them back. I'm sure someone will chime in with the right answer.

[Captainfab]

No need for shorty headers.

Well there you go. I will go this route later on.

the stock big block towers should fix that they dip down to give clearance
