Sooooooooo..............is a tall deck a good engine for a boat ?
It's a great base for a stroker engine, you can use longer rods. The "stock" 454 truck tall deck is a truck engine, 4 ring heavy piston, not designed for performance.

The biggest issue is if you want to use your same intake and distributor, you will find they don't fit. You can use spacer plates for the intake, but still need a tall deck distributor, or you can buy a tall deck intake, many of which now will use a standard distributor.

As I told you in PM,, something seems not right. Stock GM 7/16" rods would require the use of a "truck" piston, similar to the stock 4 ring model. Certainly not a "no expense spared" kind of engine. The "oversize valves" may be covering up sunken seats in a truck oval port head.

This one would require careful inspection prior to purchase in my opinion, including but not limited to removing at least one head, and probably the pan if it is bolted on.

2 Sav, you changin your mind again??? J/K

No.. it would have been a half the money down thing and payments. I liked that idea , get a motor in the boat this season:)devil

But thanks to the few...."You know who you are":)hand that set me straight. It dont look like i can take any shortcuts , and nobody else wants to sell one on payments.....

Too risky i would think:)sphss

The GM Rod with 7/16" bolts was the racing High Performance rod, generally only found "stock" in the L88 427's and the LS6 and 7 454's.

Both are 4340 steel alloy
P/N 14096151 in a pressed pin style (knurled shank bolts, LS6 & LS7 454's)
P/N 3969804 in a full-floating pin style (the HD racing version) 7/16" ground Boron Steel bolts. Green color coded rod, top of the line.
