Thread: 396 375hp build question

Tweet

I am glad people are realizing....there is no'good pump gas fuel' and I will
agree 10/1s are stretching it as far as detonation..I had a sbc 350/4 bolt main
with 300 heads,had a crower 480 lift cam,great to drive and 89 octane to boot
on 9.8/1 compression!You are asking for trouble with true 11/1 compression..
engine maker try to get you to buy these'trouble makers'but you have to mix fuel
etc etc etc...to get octane up..nothing like a ping motor or laboring motor
that you can not fix 'even with timing addjustments' people need to live in the
'now' unless you l;ike headaches..GFD.....

Another easy way to tell if it's a forged crank or not is to hit the counter weight lightly with a hammer. If it sings like a chime it's forged, if it makes a "thud" sound it's cast.

I'm currently building a 396 350HP for my '69 El Camino. Block and heads are from '67, heads are closed chamber oval port, pistons are a 19cc dome, solid cam with 240@.050, 10-1 compression, ported heads flowed 270cfm @.550 lift, has the forged 366 truck crank(rebalanced), 750 holley, Air Gap RPM intake, desktop dyno said 480HP-490Torque not accomadating the port work. The heads also have the chambers polished so I'm hoping to run on 91 pump gas. Just can't wait to drop it in. Hope this info helps on your build.

Don't be hitting any cranks with a damn hammer.
If I saw this in my shop I would have to use the hammer on someones head.
Like I said before wide "parting line" it is forged narrow "parting line" and it is a casting.
