Have any pic's send if you can to [email protected]. Buddy needs a pair.Thanks JOHN

bigboat28 09-23-2014 02:05 PM

They are in Ohio, just East of Columbus. I am not 100% sure but think the timing cover is aluminum and they have mechanical fuel pumps on them. The port motor just got a new oil pan gasket, a timing cover gasket and a new front main seal. That was done about 3 weeks ago.

bigboat28 09-23-2014 02:07 PM

Fenderjack, will try to send pics tonight if I get out of work soon enough, if not tonight might not be till thursday.

Irishtornado 09-23-2014 03:06 PM

The foundation of the 454 HO is a brand-new, updated cylinder block, which incorporates many strength and performance design enhancements – making it a smart and economical alternative to rebuilding. We also add an all-forged reciprocating assembly for maximum durability, a roller camshaft, and a set of rectangular-port iron cylinder heads.
We deliver the 454 HO with a water pump, balancer, 14-inch flexplate, and aluminum intake manifold. Add a carburetor, ignition system, and starter and your budget Big-Block will be ready to roar. All of the necessary parts are available from Chevrolet Performance.

If you want the strength and convenience of the 454 HO bottom end, but want to add your own heads and induction system, use our 454 partial engine (P/N 12498778).

Would like to discuss possibility of long blocks minus intake and carbs as I have pair of dual planes and rebuilt carbs of my own if that might be amenable to you?
