ok 86blkconv what computer are you running, because i put a rering kit, and 351W heads w/ 60.4cc com. chambers, and mine idles like ****, your ignition and fuel and timing, just every detail would be helpful
honestly i dont know what computer is in it, i would imagine it is the factory 86 speed density computer in it. i will have to look and check it out. for the fuel pressure im am running 42psi w/vacuum off, and the timing is 16 degrees when i know im not spraying it and about 12 degrees when i know i am spraying it! TPS right at .980! i set the idle right at 1000rpm and it idle's pretty good!

your better off upgrading the heads and intake first you'll get more power that way a 347 is just gonna get you some torque and move the powerband down you'll only gain 10hp with stock heads from a 347

back in the day a 351 crate motor with e7te's was only 235hp.
but really lets think about it, stepping to a 347 your increasing stroke .4". your running a 4"bore still with the same pathetic heads, hp wise you'll just make the same numbers 400rpm sooner. you will gain torque because torque is in fact a function of stroke and cubic inches, hp however is not. hp is based on cfm not cubic inches. this is why i said get better heads and intake- cfm- airflow
so in theory it wont make 10more hp but i think it will but thats about it. change the top end components and its a whole different ball game but stock e7te's are door stops they dont flow very well

Just stole a used 302 block off a guy for dirt cheap that i'm planning a 347 build with, i already have a set of refurb'd e7te's... If i were to get the heads ported and the whole nine, would i be able to get them to flow good enough to get some good gains from the 347??

I'd be utterly embarrassed to say I had a 347 putting out well under 300 hp with that combo
