Inliners International Forums General Discussion Hi Performance inline 6 v/s v8

Hi are there any inline 6's out there running against v8's in circle track dirt racing if so how do they compare. i want to replace my v8 with a il6 and whip the v8 but not sure what to build i run on a 3/8th mile dirt oval with slight to medium banking. 350 flat tops, 480 lift 882 heads stock size valves, headders, 4 brl carb and a powerglide turning 5600 rpm with a 6.24 final gear.
please help guys and thanks in advance.

we have many dirt & ashfalt guys here in Fla But not sure any are online to help you with that.and i know of one that also runs a flat head.If you want to Email me I'm sure they would be willing to let me give you their phone number. and be willing to help you out. }[oooooo]

bubba, For a 1/4 mile track you would have a chance. I've seen it around here. The six will come on harder coming off the corners and the V8s will just catch it at the end of the straights. But for a 3/8 mile track I'm afraid the six won't be able to hold off the V8's. That track will give them too much time to wind it up.

Why stop at just considering an inline six? There are inline four cylinder-powered cars that will match 6 and 8 cylinder race vehicles...oval-track and straight-line racing.

It depends upon consideration of a multiude of variables...

Allowance of aftermarket engines/components by the track or sanctioning body.
Allowances of aluminum engines (OEM or aftermarket) with multiple cams.
Allowances of the engines themselves to have the ability to make more power....more compression, higher octane fuel, roller components, etc. and not allowed for V-8 engines.
Weight or chassis build advantages given to smaller displacement engines...lighter chassis and components, wider and softer tires, etc.
The financial ability of the racer to make a smaller displacement engine compete against traditional V-8s.

Finally, the track itself. Being a dirt track, is it soft with lots of grip or dry/slick? A V-8 cannot use it's available horsepower if the track does not provide adequate grip and all other things listed above are equal.

Hey bubba, what class do you run in? I have seen an inline take 3rd in a 100 lap feature running against big blocks and strong 350's. It all comes down to setup. Do you have a weight rule?
