[DeTomaso] Aluminum 351C stroker for sale

[Daniel C Jones]

Ford produced both aluminum 351C and 351W blocks.  The 351C blocks
tended to be used in drag racing using matching aluminum 351C-4V
heads and the 351W blocks tended to be used in road racing (early
Can Am and the GT40 program), usually fitted with Gurney-Weslake
heads.  One of the guys on the 351C forum remembered watching Wayne
Gap match race Larry Lombardo in Bill Jenkins Monza with an all
aluminum stroker Cleveland in a Pinto back in the 1970's. Some of
the blocks are said to have had 302 mains.  Both the 351W and 351C
aluminum blocks were cast well before their production cast iron
counterparts hit the streets.  The aluminum 351C block pictured in
the links below is has a casting date of 10-22-68 which is well
before the iron 351C was sold to the public.  The block has an SK
part number (SK-42167), along with an #A3 change level. SK is engineering
shorthand for sketch.  An SK part number requires less production
engineering paperwork and analysis.  Likewise, XE stands for experimental.

Notice the 6 bolt per cylinder head bolt pattern.  The matching
aluminum 4V heads for the block also had six bolts, though the ones
pictured on my page had the sixth bosses milled off.  The bore on
the block pictured is at 4.1".  I've been told the standard bore on
those blocks was 4.08".  Note that Jeff's block was damaged (forward
lifer area) and repaired.  The lifter valley was weak and would crack
in that area since they don't have valley stiffening ribs like a
Fontana aluminum block.

The one on Mike's page appears to still have the undrilled bosses for
the extra head bolts but isn't using them with the Brodix heads.

> What headers would you use?

It's not clear which series of the Brodix heads those are.  Brodix makes
both the BF200 and BF300 series.  The BF300 and BF301 are clones of the
old Ford Motorsport C302B heads and Pantera headers for those are available
from Byars and Larry Stock.  The BF200 Series are Brodix-Neal  The Brodix
Neal heads are competitors to the Yates C3H and FRPP SCI.  Like the C3H and
SCI, they have higher raised ports than the standard C3 and C3L Yates heads
at least on the intake side.  I've not has a set in my hands to measure the
exhaust port pattern but, IIRC, Brodix recommends the same Fel Pro FP 1431
exhaust gasket so at least the bolt pattern is the same (port location may
still be higher).  In Mike's pictures, it appears there is some sort of
a exhaust flange with very large oval openings bolted to the heads.  Note
that while the heads say Neal on them, that doesn't mean they are BF-200
series.  BF-300 heads can say the same thing.  The intake appears to be an
Edelbrock 2991 Victor-Y which is for a 9.2" block with C3 Yates heads.
