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.

Some have Qjets :)

Re: 327 --250 hp
 

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.

Re: 327 --250 hp
 

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

Re: 327 --250 hp
 

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.

Re: 327 --250 hp
 

I don't know how much power it made, 'cause I don't dyno, but Steve Tschetter went 10.63 @ 124.67 in SS/LA at 3450 lbs. back in 2000. That is the '64 Chevelle Larry Wilson now has but the times were done with a stock block around the same combo Larry referred to.

I didn't have anything to do with the Bowtie version of that engine (other than storing it in my garage for Steve), but I was surprised that I never saw any times close to the 10.63 after it was sold. Larry, did you go faster than that?

Jerry when I purchased the car the people who owed the car tried to put it back on the street. The motor had 8 cracked pistons and the cylinder walls were seriously scratched. I re-did the motor but it never ran like it did when Steve owned the car. I only ran 10.60's in K. I put a stick in it and it ran a lot better which makes me think I should of checked trans and converter out. I didn't know Steve but he spared no expense when he did this car.

Most of the time 2tenths. The motor I run is the 62 version 4 gc 520 heads.

Re: 327 --250 hp
