My plan is to put the motor in the car and run it as is.
we're replacing the vavle springs and checked the bearing

It is a Bow-Tie Block build 640 hp on the dyno
Crower Crank
12 to 1
weisco piston
Oliver rods
all-Pro 23 degree raised runner heads 245 spreadport (ported)
It has a crane cam 118251
the specs said 256/256 Duration at 50 (the engine builder specs showed 262/ 262)
lift 625/625
Lobe separation 106
it is a dry sump motor, which i will use if it fits under the chassic
It has a Bowtie intake ported to match the heads
He ran an 850. I'm going to run an 830 HP Hollyon a 2" spacer

It is an older motor that was not used much
I looked up the engine builder Brian at Duratech in Coopersvill,MI he said I would want to go with a larger camshaft for drag racing. The Motor was set-up for a short track 1/4mile where they wanted a quick response out of the corners

Got to get a new set of headers too.

Got a 55 chevy 3500lbs with driver and cast iron heads (old motor) will need to add a 10 point cage so that adds some weight too

turbo 400 4000 stall

Looking to run 6.5 1/8 mile n/a

I was thinking a 1050 dom. and a bigger cam

Thanks in advance

You check leak down on that engine?I would definately put some more cam in that thing.I would be pissed with those numbers on a 355.With those heads that thing is 100 hp short easily,on a 420 cu.inch.Put a moroso dominator adapter on that intake and match intake and spacer .And get a 1050 dom carb and wake that thing up.

I thought hp was low too,i bought a -10 Brodix Neibel Racing Engines,dirt track 421 a few years ago that my engine builder said should make 690-710 range but parted it out and kept the heads.

I see the ops engine has oliver rods which are probably 720 gram rods ,I did 5.850 carrillo rod 4.125 bore x 2.800 stroke engine with same head that did 706hp and its 120 inch smaller .It went 6.15 in a 3200lb car.Brodix restrictor heads like ascs casting do 290cfm and will make 700hp on a 358 cu in.
