That's a (better) wrap

You may recall (or most likely you don’t) in my last post I had wrapped the headers but wasn’t too happy with how the driver’s side one turned out. I had wrapped the two center pipes together for what could be considered way too far and it was generally ugly. Now having twice the experience as I did when doing that one (as in I did the other header), I unwrapped those two pipes and redid them after work today.

That looks much better, I’d say. Still had to double up on the top since the pipes don’t have room between them where they meet the flange for both to be wrapped individually (there is a single layer of wrap between them, at least).

I also picked up more stainless ties today, so these are officially Done.

One step closer to having the engine bolted in - my goal is to have it in place by the end of the year (which then leaves me a bunch of time to put the car back together around it... hopefully).

Nice, that wrap can be tricky to get right but these look great!

Looks good.

How does a wrapped header compare to a coated header, in terms of under hood temps and sound?

I imagine a coated header will likely Outlast in terms of corrosion resistance?

Thanks! A wrapped header will emit less heat and noise than a coated one, but is more susceptible to corrosion. A wrapped stainless header is probably the best of both worlds I’d imagine; these are just mild steel.

That’s what I was thinking.

Nice, what's the vehicle application?

Going into my ‘71 chevelle mali bu sedan, in front of a 4-speed. AFR heads, solid lifters/decently big cam , 10.5:1 compression, should be a good time until I blow up the rear end :)

Haha I like your confidence and real-world expectations. I'm guessing a 10-bolt out back? Hopefully not an open diff? Did you at least bump up the axles?

Completely stock, open 10 bolt. Next winter most likely will see it being replaced with a LSD’ed 9-inch. Not doing it now because money (and time).

Awesome, that'll make for some interesting launched. Good luck! Can't wait to hear more about progress.
