Having major issues with my new rebuilt motor..
I have got my 351 clevo fully rebuilt but cant start it. Keeps backfiring as soon as u accelarate ever so slightly..
Got a funny feeling cam timing is out....
Heres the run down...
2v heads 4v valves
750 double pumper quickfuel carby
Edelbrock air gap manifold with 2 inch spacer
Crane gold roller rockers
Jp racing geardrives
Crane f246 solid cam
Ignition is working fine.. all electrics have been checked. Carby has been tested too .
It has to be internally....
I have dropped car off to engine builder but he has stuffed me around for 6 weeks. p****d me right off so I really want to to this myself..
Ive been told that I can check cam timing easy by pulling off rocker covers. Setting no1 cyl to tdc and checking another cylinder to see where rockers are sitting at but I cant remember what to look for...
Does anyone have any info before I remove timing cover..
"I usually downshift when I'm near a Prius so they can hear me hurting the environment"
easiest way is to put the motor to TDC no1 compression, and see if the valves are rocking on no1 cylinder.
