Dear Jim,
I am using standard 4.6 heads, not ported. I bought the block as a short engine from Chris from RPI. It was a old project that was running once for a short time but the customer didn't finished his project and he kept the engine for himself.
The pistons have 94mm and on its crown there is a stamp that says .020 so i think they are oversized.
The crank is a 4.6 but the journals of the conrods have been resized and outcentered and the stroke was increased. It has approximately 4.8 maybe 4.9 now.
Chris told me the conrods are some special thing and all in all it is a well made bottom end.
I do not indent to achieve the most possible from this engine, the price for the whole bundle was good, that's why i bought it.
I plan to use the standard 4.6 heads, all the 3.5 ancillaries, the 3.5 manifold and headers but 2" HS8 carbs to avoid it running lean on higher revs.
Chris suggested a Piper 270 cam and its already in now.
The head have springs fitting the camshaft, new rockershaft, new cam followers, ne pushrods, improved oil pump etc..
Yesterday i bought a complete package of LT77 with bellhousing, remote and stick
That's the route to go...
