yeah?? i cant hear any pinging etc and wouldnt that make my plugs white? ive always leaned towards timing i checked it a while back but ive tutooed with it again since. im thinking maybe weights and springs need changing in the msd?and maybe thats why it idles nicely cold and that it could be compensating.

Hey guys i am having a continuing problem with my 302 cleveland, being backfiring out the carb. First a quick run down..... standard cam and heads, edelbrock performer manifold, holley 600 carb, 65 main jets, rebuilt carb, new pump cam, new pump, all adjusted properly (i think). squirts heaps when i look into carb and immediately. carb spacer, new hei distributor etc. The car starts mint, with the slightest pump of gas. idles fine without choke even when stone cold. idles at 1000rpm (manual) and has about 22 showing on the vac gauge with a steady needle. ive done a compression test too with no more variance over 10% of each other. Pretty much the car runs sweet when i drive it, under load and i feel the secondaries slowly ease in, as i should be. but when its parked and in neutral if i floor it flat it will stumble and backfire out the carb and stall, however if i pump the gas up and down quickly, it roars and revs right out. why does it stall when not driving and yet when i do it flat when on the road it kanes it. Does this mean its leaning out? and the secondaries are giving me the extra fuel needed when they come in? ive got no vacuum leaks i know of. but the curve ball is when i pull the plugs they are fouled to fuck. ive tried the timing in all sorts of places. but i havent played with advance curves etc yet but surely out of the box it should still rev at all stages your thoughts are much appreciated cheers jason

My flatmate is an engine builder and his dad has clevos but both have differing opinions. Its a bit of a trial and error scenario that's why was kinda keen to hear from anyone who has done it before to a cleveland specifically. Apprently on a windsor for example it'll run poo, but because clevos have such huge ports anyway I've heard it doesn't cause an issue, if anything it makes power. Cheers

Hey guys Have just gone to fit a 4bbl factory cast inlet manifold onto my 2v clevo but I've noticed my 4bbl manifold I'm fitting has 40mm ports roughly and my heads and old 2bbl manifold are roughly 32mm ports, obviously this will have a huge difference in port matching. My two questions are, Has anyone done this mod before? I've heard clevos thrive from this and that its a good idea, But just rule of thumb I thought wouldn't be a good idea at all. Secondly, if this is ok then what gasket would be best to run, I.e one that matches port on head, or one that matches port on manifold, it would be best to get one suiting head I believe Please I'd prefer to hear from someone who knows clevelands and has experience with this problem as I've heard from all the old boys That they respond to mods differently to other engines haha and what may be a problem can sometimes not be with a clevo and vice versa Thanks Jason

guys can anyone on here tell me if my 289w/302windsor sump will bolt directly onto a 302cleveland without any modifications? save me buying a new sump for nothing, thanks

They are quite abit different to the mk3s, as mk4s were v6 factory and had spare wheel in engine bay etc....the mk4s had the good gbox that can handle v8 torque also. I heard the mk4 zephyrs were meant to be factory fitted with 289 and 302s and the zodiacs were To get the 351s, until some pommie gitt told them to run the essex v6s, which are absolute shyte. Can anyone put me in contact with someone who's done the conversion in a mk4, would like to pick they're brains Cheers boys

Haha thanks for the info, apparently they were quite the boy racer car back in the day, but yeah I've heard about the shocking body roll. Having it slammed should assist with that issue, also being a 71 its got disc rear and independent rear end so ill get the handling sorted. Did you help build the one at the uni? Or if not is there anyone you know that wouldn't mind me having a chat to them Thanks mate Jason

hey guys just wanting to know who on here has done this conversion before? im doing it next weekend and apparently was quite common back in the day. my only real question is im going to run the mk4 4speed box factory from the zodiac, so which bellhousing do i run to mate that to the 289w??. i want to do it original without any adaptor plates etc, ive heard theres a paticular bellhousing that bolts directly upto both, everyone just cant remember what car they come from. do i just run a mustang bellhousing? but i pressume theyre bolt pattern will be too big for the zody box thanks alot Jason

as above im putting back together a rwd 323 engine its a 1300. does anyone have the torque settings for the head bolts? much appreciated cheers

shot man

hey all whats the stud pattern for my rwd mazda 626, cb2 model, cheers saves me going and taking a wheel off
