This is just for fun and something I most likely wont
know unless you base it on the on track performance

Guess the HP and torque
What I have is a
340 stock block with 4 bolt caps at 4.070 bore
4" stroke crank turned down to chevy rod size (2.1")
6.125 Eagle H-beam rods
Diamond pistons with a 18cc dish and valve pockets
which will be either a 10.75 OR 11.02 compression
depending on which head gaskets
cam is a roundy round solid roller 260/270@50 .610/.610
lift on a 105 LSA installed at 105
TD rockers with push rod oiling 1.5/1.5... but I'm
checking my stash to see if I have any 1.6 intakes
W-5 ported heads.... 2.08 intakes, 1.6 exhaust both
are .343 stems peak flow is 310 cfm
M1 intake with 4500 adapter and a 1050 dom, match
ported to the heads
custom wet sump oil pan with scraper
1 7/8" headers

This is a pump gas engine
I think thats about it.... take a guess.... this is
going into my Rampage... this will be my Hot Rod
Drag week car and my street hot rod ... I expect it
to be at or a little less than 2800# with me

I know it isn't a full up race engine, but I know a guy that ran a 422 CID, small block with W5 heads, and it was way faster with his W2 heads. But that isn't fair as the W2 heads were heavily ported, and much smaller chambers (CR). As I recall, in a roughly 2700 pound car, around 10.0

As a guess myself I'm thinking 550hp with 500tq I might
be a bit high but I'm hoping for 500ft lbs on torque
I'll be running a 518 OD trans with a 4500 stall
or there about converter( I think it would be closer
to 6000 but I'll send it out to have it corrected
to my engine).... I can only run 10.0 at ANY track
and 10.80 at the Hot Rod week stuff

I can NOT get a NHRA license anymore due to health reasons
so I am limited to 10.0 MAX... and in this participial
field they have a 10.80 cut off with a average of
10.80... BUT they deduct .1 from your weekly average
