Author Topic:   heads... 882's vs 601's
posted March 25, 2004 08:04 AM           

I'm running a bomber car with a .450 lift cam rule and pretty much stock everything. Automatic transmission, cast iron manifold. This is a 3/8's track with medium bank and pretty tacky.

I have a set of 882's ready to run on my 350. I also found a set of 601 heads from a 305. They have 58cc chambers and 1.84/1.5 valves. Oh, and I can pick them up refurbished for $50.

Are the 601's the "GOOD" 305 heads to run on a 350? Or would I be better off sticking to the 882's??

People have won many races with both.

Being stock everything as you quoted, I would think you are not going to be turning to many rpm's, so the 601's would bump the compression.
But if you plan on turning this over 6,200 or so rpm's the 882's might be a better choice.

For $50 you better not pass them up! Yes, the 601's are the good ones. They will pull pretty good up to 5500ish rpm with stock valves. around 6000 if you put 1.94 and 1.6's in.

With a typical flat top piston, the 882's will give about 8.5 CR. The 601's will give almost 10.5 CR. 2 CR points is worth about 10% across the board (at all rpm until airflow becomes an issue).

i'd run the 882's your not running much cam so choking it even more with the small valves isn't something i would want to do

I ran stock 305 on a 1/4 mile track at 5800rpm,then put on 350 heads. The 305's pulled better off the corner but did not pull as good past the flagman. Over all I liked the 350 heads better and stayed with them,lost to much top end power.

i have used both also but the 601's really need to be ported to get any flow out of them

Ok... here's the deal...

set of refurbished (then slightly used) 601's AND a used Edelbrock Performer Intake #2102 (this is the one our rules allow)... both for $75.

I figure the intake alone costs over 100 from the store.

good deal, right?
