Any 427 Chevy fans here?

I am a Mopar fan but I think I scored big on some Chevy BB heads...... I went to a yard sale found a brand spankin new never been installed bare aluminum 427 head part # #3946074 and two old well used 427 iron heads part #3964291

On a Google search the aluminum head #3946074 I found this info High performance, 69-71 ,open chamber 118cc, Hi Perf. 375 L-89, 430 L-88/ZL-1 465 LS-6 and 7.


The Iron heads also come up with a Hi Performance application,
3964291 1969-70 396/402/427/ Closed 109cc 396/402/427/454 large or small spark plug, they are bare have a recently been bead blasted and probably need guides and seats and seats ground , still they are a good start for any one in need of HP heads.


Anyone want to gander what there worth? I'll trade for a coal stove or firearms

jackman, put a set of solids in her--the hydraulic lifters had a tenancy to float out at 5 grand.

The closed chamber iron heads are certainly desirable for a performance build with STOCK castings. Ebaymotors would probably be your best bet, or try a local hi-po shop.

That depends on what you use for valvesprings. The "little" 350 in my Z28 didn't float at 7200 with hydraulic lifters, but then again the valve spring rates were around 370 lbs./in.

No solids for me I want to flip'em I only bought them cause they was cheap not a Chevy fan at all

Ahhhh, then that's a whole different story Outstanding find though---MOPAR huh?? They did make a kick ass tranny back when, compared to the old--slip & slide with power glide

I was never a Mopar fan back in the days but you got to admit they had a good drive train, awful hard to beat a good running Hemi & you could change the valve guide in their trans without pulling the tranny. Only problem was they rusted out faster than the GMs & maybe even Fords.

They still do ...


Yeah throw those heads on eBay in an auction style ad. I'll bet they get bid up pretty good, although you'll need to assess their condition - your going to get a million questions asked, & it's better to be prepared & know what you've got. EBay shows no mercy for sellers - it's a buyers market. If the buyer is unhappy, you'll have your money extorted from your Paypal account & refunded to the buyer, leaving you high & dry.

Seller beware!

Good point Smitty, it would be wise to have the heads checked for cracks and warping prior to listing them.
