It's a 306 that's based on a Mexican block that's been partially filled with Hardblok. It uses a Boss 302 crank and rods, 0.200" dome Probe Twisted Wedge pistons, and a custom grind Comp solid cam measuring 242/254 @ 0.050" with a 110 lobe seperation. Compression ratio is 11 to 1, which will be on the edge for pump gas, but hopefully the aluminum heads and big cam will keep the detonation monster away.

Most of the parts have been on the shelf for quite a while. I dug up the recipt for the pistons, and it was dated 1996! The old engine just didn't seem to want to die. If I was starting 289/302 from scratch, you'd be looking at a 331ci stroker topped with a set of AFR 185 heads built inside a Boss 302 block! But the next engine will be a 351W stroked out to around 400ci. [img]/phpBB/images/smiles/icon_wink.gif[/img]

Here's a few pictures...







Here's a picture of a piston out of the old 289 headed engine. It's an old TRW #2249 forged unit that originally had a 0.400" dome that was cut down to around 0.040". The deck of the piston has also been cut down 0.060" to allow the use of longer 289 rods. This also raises the top ring... which isn't necessarily a good idea with significant doses of nitrous...

Here's an embarrasing picture of the car anxiously awaiting a transplant... [img]/phpBB/images/smiles/icon_frown.gif[/img]



Hopefully it will be making some noise within the next month. [img]/phpBB/images/smiles/icon_biggrin.gif[/img]
