Lowered 4.5 in the front / 5 in the rear.

The Speedway rams are identical to the one found on ebay so you can save yourself some $$ and go with the ebay one. I have these same exact manifolds on my 66 C10, SB350 328hp. Mine has a 350 TH auto trans but it shouldn't make any difference on your manual trans since you'll have your muffler shop route the pipes as needed. You'll need to pick up the flange reducer depending on what size pipes you plan on using. I went with a 3" to 2.25" reducer.

Other thing to keep in mind with ram horns, get the long corvette HEI plug wires. Much easier to run them from underneath.

Ken,
I thought about running them underneath but I think I'm going to go with this look. It means I need to buy new plug wires because I have 90 degree ones now (new) but I'm nowhere near finished with my truck so plenty of time for changes.

Borrowed pic....

I will also need to find/make a set of those vertical wire looms that mount at the back of the head.

[Kenfuzed]

That looks really clean. Routing them that way wasn't an option for me since I have the valve covers with the center bolts instead of the outer edge mounting screws, so no place to fasten the wire clips. The picture below shows the wires just laying across the top but you can see that options for clips are limited with these covers.



For my setup pulling them from underneath mean less chance of melting a wire on the manifold.

[LDO]

yeah, your setup is still pretty clean though.

this is the visual i'm going for with my motor...

except i'm going to run ram horns.

I guess it's a little dumb but it's the vision in my head of what i want to see when i pop the hood....

That looks great. Let me know if you have a source for those clips. I could always fab something to hold them to the covers and would be easier than working under the truck just to route the wires (PITA).

summit racing has the wire holders but they bolt to the edges of the v/c's.

Right, I was thinking I could spot weld a couple of nuts (bungs) along the edge of my v/c's and attach those clips there. The cover design when using Vortec heads has it's limitations but with some creativity I might be able to make those work.

Best of luck with the ram horns, I think you'll really like them. I personally prefer them over headers.

Here are one style of wire loom for the centerbolt valve covers.

Summit carries the R&M Specialties wire looms.

Thanks for sharing Captain. A bit steep for me... $56 color or $105 chrome.

you may wanna rethink on those v/c and air cleaner .. i to was really into that black and red look with the Chevy logos and bought them .. what a bad mistake that was they are stamp steel and the quality is bad they are done in mass production and boxed . they never sealed right out of the box 4 different gaskets and still never sealed the v/c was not flat and kept pushing the gasket into the valves on the head .. even with sealant like gask a cinch nothing would work took them off and tried to flatten them out a bit and see it it would work ? no joy so i ripped them off and they sit collecting dust on my shelf .... save your money get some aluminum v/c with Chevy logos you will be happy you did trust me

Wolfman,
I appreciate the advice. I already had the Black VCs on my 283 that my new 350 is replacing. I had no problems at all with them as far as leaks or anything else.

I took them off the old motor, made sure all the surfaces were true and clean and installed felpro rubber gaskets and they've sealed up fine so far. I'll definitely keep an eye out for problems though.
