Performance Questions 225 vs. 360
You have nothing to apologize for,you did nothing wrong. It's all good.
The /6 vs V8 debate always gets somewhat heated. I can only speak from my experiences with the two. I spent pretty good money on both these builds,and they both run very well. They both have some of the best,off the shelf speed parts available. The slant is fun in a nostalgia kind of way,and yes everybody has a V8. But if we are talking about a shear performance comparison between the two,its not even close. The V8 will Dust the lil slant every time. Hands down.
So,the choice is yours.
Either way I wish you the best.
Johnny,
The fact that you "forgot" to add the hairdryer to your /6 is probably why you keep telling us that your 360 is faster than your slant six. If you had built the slanty with forced induction, the story might have a different ending.
I'm basing that on your reluctance to answer my quetion (three times, now) as to whether your 360 will outrun Tom Wolfe's turbo'd /6 in the video ('70 Dart, 11.02, at 3,300 pounds + driver weight.)
I'm taking that as a "no." Please correct me if I'm wrong.
As I said, that is a 9:1 compression car with 1 four-barrel with a flat tappet cam and a homemade header. NOTHING exotic at all on the car. It has a 2.73:1 rear axle ratio.
I hope and pray that our car will stay within shouting distance of it once we get it sorted out. Our engine is, as I said, a copy-cat version of his.
My other car is a 1972 Valiant that has a stock (except for the cam) 360 Magnum (see pix) with a Vortech supercharger and made 445 RWHP on a chassis dyno. It has run 9.69 @ 106mph in 1,000 feet (equates to about 11.6 @ 118 in the quarter-mile) but that was with a greasy track, a 3.55 Ring & Pinion, and some worn-out 8" slicks that were spinning all the way through first gear. My 60-foot time was only 1.81-sec... really poor. I have, since then, installed a limited-slip 4.10 and added some 9"-wide slicka, so I think it will probably pick up .3 or so in the quarter. We'll see,
But, even if it picks up that much, Tom Wolfe's equal-weight /6 car will still outrun me.
That is with 10 pounds of boost, the maximum I dare run with stock (cast) pistons.
I'd love to see you add a turbo to your slant six and see if your 360 will still outrun it,
That would be interesting!:blob:
Thanks for the discussion, and no, we don't argue... we discuss. You get more done that way.
Here are some pictures of the two cars of mine, in question:
