Fabbed up a basic belt guard - also had to re-alin pulleys for belt groove more toward the center . Needed to space the head unit pulley out. since I added a rear V pulley to the crank pulley for WP/Alternator

Thanks guys

Late in the fall I cracked a header tube. I had previously welded a crack on a pipe the year before. Basically the headers are beat and thin as heck at this point. I bought them used 20+ yrs ago. When I pulled them off last month I noticed a date 1989 - guess I got my money's worth. Hooker super comp- 2 piece- looking to replace with hooker comp 1 piece. Slightly smaller but hoping for a better fit. (Plugs, Oil filter, Starter)

Lemons would be sweet

I'm trying to go on the cheap - I trial fit some hooker street comps on the engine. They appear to clear the plugs nicely, oil filter can be removed w/o pulling header or dumping it sideways oil all over, no issue with kickout oil pan.
-The real test will be in the chassis itself -

Nice ride; thanks for sharing.

Get the Lemons. Pricey but worth it.
(AND if you look at spread out the cost over the years you have had the car.. and it appears you are not letting it go...)

They are well worth the $$, only headers I have never had to beat on to fit.

Any idea on solid mounts vs rubber? I seem to remember many manufacturers stating you need to use mount x (68 chevelle rubber mounts) in order for their headers to fit. I'm running solid Moroso's.

Are you running solid? - my guess is you have a plate front and mid.

Basically concerned with engine height and clearance issues

I am currently still using stock mounts with solid Mororso mounts. I use a poly trans mount. My headers fit perfect. Dan Lemons will tell you what you need and what will fit. I had to use a particular starter. I have 2 1/4 primary's and 4" collectors

Pretty sweet setup there - and similar to what I envision. originally I had a full sized tq starter - now mini mini. Glad to hear about the solid/stock like I am.
