You're truck is going from to that will be kick butt!

holy crap that is a lot of $$$$$$. I know its heavier, but I wonder if a 24v Cummins could have been had for less...

aluminum rods? plan on changing those out in a year or two tops eh?
So why less lift outta the cam? More duration eh? what was the old duration?
The new one is 286/292 advertised?
Sounds like it should be a thumper. My 469 BBC is built pretty similar to yours.
Its around 575+ HP/TQ.. ran a mid 11 @ 118 last summer in my 3380 lb '67 camaro..

 

[white_knight]

The aluminum rods will be changed at the end of the season.

We had an opportunity to pick this engine up for about the same it would have cost us to rebuild the old 468....so...we could not turn it down....We do expect it to have a lot more power than the 468....... It was tired......

I have a feeling I'll need an extra set of undies though

 

[SUBFAN]

The aluminum rods will be fine longer than that....Just don't lean on them when cold.

My experiance with stainless fasteners has been bad. They all seemed to loosen up all the time. Is this typical, or just my luck????

 

[walla2k5]

Holy cow!!!!! I NEED a ride in this monster!!!!!

 

[Storm Trooper]

Just one comment........



Sweet
Gotta love that BB power.

A good set of aluminum rods will last 100,000 miles in a dd, and weekenk warrior. I know they do in pontiacs atleast(oliver rods).

I hear a lot of controversy on the aluminum rods. We are going to see how they do this season. They are huge
