we finally got a converter made by ptc a 9.5 3500/3800 the car ran a best of 12.59 on the weekend at 105,the old converter was a 10.5 tci,its running close to its potential now,maybe some head work,better diff gears and a manual valve body and car will go even better

yeah this is what had me confused,dot to dot it went in at 102,so i moved the crank keyway sprocket to where it says 4 retard,re deegreeed it in and its now perfect at 106,i now understand that the 4 degree advance is the difference between lobe sep and intake centreline

I just installed my new comp cam 285 extreme energy high lift hydraulic in my freshly built 451,here,s the problem the paperwork i got with the cam states that comp grinds these cams with 4 degrees advance for optimum street use,so anyway i line the dots up perfectly inline and centreline it in...

headers on one side are coming off,because there crushed,putting a new piece in ,sump is dented,need a new ralleye,i know 340,s are quick,its great to be scared by mopar power,this thing gets on the revs so quick because of the roller cam,my brother says he doent remember anything except being...

mmmm hi guys changed the springs in the msd and then retuned it ,went from not being able to spinning the tyres to frying them and mounting the curb and buckling a front rim and busting 3 tyres,this thing dead set hammers ,its gone ballistic i think this was definetly the problem ,12 sec...

i am ready to buy my converter for this engine ,on the information i have given,what converter should i buy,i am buying an off the shelf converter from mancini,so either a coan,a tci or the turbo brand what ever that is,cause i live in australia i dont want to get one custom made so it has to be...

thanks guys alot of good info to digest here,of course we will do the simpler things first like timing and carb adjustments,when we bought the converter we gave them all the cam specs ect and they apparently built it accordingly at 3500,i get a feeling this engine could run the numbers just a...

this hp series holley was brand new out of the box and and seems to squirt a god awfull amount of feul when u crack it ,maybe it needs jetting down,maybe thats why its so doughy off the line,i think it will be off to the dyno

compression is 10.2 to 1 and rear end is 3.91 8/ 3/4 his wheels are widened ralleyes 15 inch,with mickey thompson street ets,about 9 inch,s wide i think,i think he,s scared to rev it,the motor was well built,everything measured and puttogether right,does the mile an hour suggest a better...

probably only leaving the line at 3000 rpm,i think you gotta rev the crap out of this motor to make it go,the cams pretty big

thanks for the info on this guys,i now understand it much better,i am going to get my line honed anyway on the mains cause i,m going from factory bolts to studs,but i was really hoping to get away with leaving the cam bearings in there and just fully cleaning the block in a none caustic...

hi i was just wondering why you need to line hone your mains when you install studs and you dont have to when using bolts,i am putting a girdle on the bottom of my 451,overkill i know ,but the whole kit was only $335 from mancini and the studs alone where $100,so i went with the kit?

72 bb swinger,what has your car run exactly with this cam and what stall have you got,what carbie,i,m trying to avoid a holley cause there like chevy,s everyones got one and i,d like something different ,is there an optional carbie as good as a holley,would a 800 edelbrock be ok?

i suppose i could go a solid cam,but i don,t want to be setting the tappets all the time,on camquest,the solids didnt show up any more horsepower than the hydraulics,is that program accurate?i,ve got the 1/2 inch pickup,and i ended up buying the hughes rockers,they dont look much,but i geuss...

thanks for the votes of confidence guys,sounds like theres alot of respect out there for these 451,s,cant wait to start my build,was thinking of running a edelbrock rpm dual plane,but i,ll think i,ll go with the single plane with this cam because it doesnt seem to start working till 3000rpm...

yeah i geuss i could of gone bigger,but i,ve bought the kit now,plus i only wanted to use stock size port heads,a 500 inch would probably need victor raised ports or better breathing capabilities,which would of been even more expence,offset rockers ect,i,m happy to be building the legendary...
