6cyl and v8 brake boosters

[Guzzoline addict]

Hi all ,Is there any differents in diameter of a v8 brake booster compaired to a 6cyl.If so how much by?The reason i ask is that i have tall rocker covers and it is hitting the 6cyl booster.

I run a VR booster and have increased rocker cover clearances, maybe a VT one might give even better clearance

cheers

i reaallllllllllllllllllllllllllll

lllllllllllllll


llllllllllllllllllll

y
doubt that they would hit

[vkberlina]

not unless the motor spings backwards

? At the moment it has standard commodore engine mounts,why would you say it wouldnt hit?Is the the booster further back on the v8,s?

[ari666]

well i have tall rockers and there is about 3 inches of distance between the two.

[ari666]

ignore the crappy flames,


i can get my arm in between the rocker and booster. prolly more like 2 inches that 3. you must have really tall rockers, or your engine mounts may be on the wrong sides.

Dude u MUST have it fitted wrong or something ther is a pretty big gap..

Had another look at it today and still can't find the reason why it so close.I changed the brake booster to vh 6cyl i had lying around ,it was further away but only by about 5mm.Does the arrow on the gearbox crossmember point forward or back and is vl mount brackets higher?the ones i have are 57mm.

i couldnt tell you, but if you put the engine mounts on the wrong sides im pretty sure itll stop the engine from dropping about 2 inches.
