350 vs 327

I think that all that can be reasonably said about this issue has already been said.

65smallblock Machine shop Tom and Johnsongrass1 know what theyre talking about. Yes a 350 given equal parts will make more bottom end than a 327,and yes dispalcement and torque are the simple,safe soloutions to building an effective street machine. However a smaller stroked motor can be made to generate uncharacteristicly high HP numbers in the upper end. For someone who knows how to use it this is also very effective. Take for instance a 60's era chevy II with a l-79 350 hp 327. Those little critters were big block slayers, why? because they were set up properly.. Lightweight chassis with proper gears and engine internals are all key. Same with the 302 Z-28s.

There was a guy at my high school who shoehorned a 327 under the hood of an old VW bug. Major custom fabrication and customization. The steering wheel extended way back and the back seat became the only seat. I watched that little bug smoke many bigger cubed muscle cars at the strip.

Its not a one size fits all proposition like building a stroker or big block, but it works.. It also can be more expensive to safely make 7000+ rpms, but that is where a shorter stroke begins to show its worth. It is not as likley to grenade at high rs as a 3.75" stroke.

454C10 327 dreamers always make me chuckle.

Hello...It is just a nice sounding number guys. Just like a 427 or a 396. During that time chevy was making slogans from their cid values. It was just advertising.

The real power is all in the heads. The block just needs to hold together. My 350 revs to 7200 rpm with out any problems because it has the cam and heads to do it. Even a "magical" 327 can't rev like that without the right parts. Maybe a 327 revs a little better because it doesn't run out of cylinder head as quick as a 350 because the 327 isn't making as much HP. And have you seen a stock 327 piston! They are very heavy and long as compared to a 350!

The same thing goes for 427's and 454. If built the same, the 454 will kick a 427's butt everytime.

I have had 327's and 350's. 396's, 427's, and 454's. And every time, more cubic inches make more power.

Maybe the 350 could beat a 327 on the street, but not in the quarter mile

Mad Maggot another thing to consider, smaller engines are more challenged to achieve power when they need to spin at high RPM. They must overcome greater friction and other power robbing forces from spinning faster, which makes the displacement/RPM power ratio disproportioned a little.

killerformula yeah you missed the point. Part for part a 350 will ALWAYS beat a 327 on the street. Always, not sometimes, always.

alls i know is that i have a 327 sittin in my garage that will blow the doors off of any 350. The 327 has a shorter stroke, which lets it rev up to higher rpms. When i drive this motor, Im not scared to race anybody because most of these people like riceburners easy competition... I know most of you wont agree with me but this is all just my opinion.. But i know that their is not any 327 out there that can not beat a 350.

johnsongrass1 From racing experience, I use a 331(.030 over 327) in my modified dirt car. Just as Tom said, we are slower on start's at 4000 till she revs till 7500, And that's with heavy piston(I know It won't last long). Other driver swear by there 383's and 406's and a few like the 358's. I find it easier to keep from buzzing off the tires with less torque but with 6:30 gear it'll pull with any 406 turning 68-7000. Heck, One guy even uses a 4.3 sixer with a 6:70 gear! For street use it's hard to justify the needed rpm of smaller engines but I think it's all in the combination as far as which is better for the intended usage.

machine shop tom For a long time (about 20 years) I had a 327 in my car. It was 11:1, had the Z-28 solid cam (30-30 Cam), Z-28/LT1 intake, 462 cast 1.94/1.50, mildly ported heads, 650 DP Holley. Ran good.

I changed that motor out for a 350 (+.040") with the same carb and intake, a little less cam (370 HP LT-1 solid), same heads with 2.02/1.60, a little more porting, comp about 9.5:1.

I can't say there is much differce between the two. The 327 pulled a little harder past 4500, the 350 is torquier from 2500-4000. Just a you would expect.

pontiac owner Yes, do go ask about it now. You will kick yourself if someone else gets it, especially for a song, or it just deteriorates into the ground, and then some junk man hauls it away and crushes it.

454me When I was young we were a Ford family. At one time we had 6 mustangs from 65 through 68 in the family. When I started looking for a muscle car I didnt even look at fords. Why, it was way cheaper to go chevy and parts were more common. I really enjoyed my 65 mustang but the engine compartment was just too small. that 289 seemed to fill it up and here were the chevy guys running 396 camaros and novas. I know you can shoehorn in a bigger motor but it wasnt common back then. Im talking about 1970 or so. There is a house close by that has a 65 mustang fastback that they have started to let sit outside and I have been tempted to go ask about it.

pontiac owner We sold 2 of them to people we knew and who know where thay came from. They are still driving them. One has past 300,000 miles. The people still talk to us.
