327 --250 hp
 

Anyone care to share thoughts on how much power one makes.??

Re: 327 --250 hp
 

Mine made 520-440 hds-up heads(54.8cc), gm bowtie blk, stk crank, 2-ring miller pistons, stk cam bore. Really nothing special ran .6 tenths under '64 chevelle in k. I think a good one makes around 550 hp. Larry Wilson 3058

I take it you are talking about Super Stock motors with a 4gc carb. Back in the day when my 283 520 head 4gc carb made 500 plus hp .95 under with todays indexs. 292 when you take bore and stroke = 1.71 hp per cubic inch, it would mean the 327 should make 560+ hp but there are lot of other factors into it also.

There were three incarnations of a 327 250 hp engine.The first was in '62-64,it had the 520/896 heads, the.398-398 lift cam, a 4 jet or a WCFB,and a skinny plenum intake.
The third version was in '65.Same short block,cam,carb and intake,but with 461 heads.
The third version was in '68.It is a large journal motor,has a .390/410 lift cam,#290 heads, and is about 9:1 compression, has an iron QJ intake with a Quadrajet.It came only in Chevelles, big Chevies,Impalas, wagons, etc,and pickup trucks.They were more common years ago, some of us still run them.They are pretty user friendly.

I was speaking of a ss motor. I have one, never made over 505 . Never ran better than 55 under 3200 # hetler heads deno carg pg or 3 speed not a real low buck engine but not in the 28000.00 range either. Have heard they have made in the 600hp range.

600 HP? What actual combo is this 327/250? There's about 3 or 4 of them.

Oh I think we'll find out eventually, Bob

I saw a split window 63 Vette at Pomona running one of those engines,it has gone 9's.How much power does that take?I think the 65 engine would be a riot in a 65 Chevelle 2 door post car.In Stock, you could switch from the 250 horse to the 300 horse with only a carb swap,since the 459 intake is legal on both.
