Cast alum. "stock" Y block v. covers

http://www.bulldogperformance.net/index.html has these.

 

Pretty cool... I like the ones with the script more though. MY bud got a pair for his Y Block that say Mercury down the side.

 

Oooooooooooooooooooooooo.............

 

Speedway and a few others have thos covvers in chrome at good price I might add...Also theres a 2x4 intake being reproduced

 

I prefer the finned aluminum thunderbird ones myself. The prices **** however...

 

Looks like a buck to cast your own,
How much over sized did you go (Shrink)?
You doing it in Al. or some other metal, Br*** would be cool?

Bulldog is releasing them and Boss 429. I was checking on their much anticipoated Olds head. I see their Cad head flows 300 CFM and they have Poncho and Mopar, too.

 

Note that those new cast Aluminum ones are 1" taller to clear roller rockers according to the website.

 

Here's another new one I came across the other day. Vintage Speed $189.00

 

Those are circa '60 Mooneyes. It hurts to pull that motor. I just want to drive it too much to deal with the Y-block. Maybe I'll adapt these to the 351W that's going in there.
