78 460 spark gap

My 78 460 is out of a Econoline.8.0 to 1 compression.I am using a single point distributor and I am wanting to know what gap to put it at..My book says .35 for single point but the 78 elec. ignition says .45....I am @ .40 right now...Plz help!!!!!!!

.035 for points - why still running points?

I got it from a friend for 10 bucks.It had about 50 miles on it.It is a fresh rebuild..

But does the compression ratio play a roll in the gap?I thought they needed a bigger spark?

Well I found my problem out yesterday.I had bought a 750DP from a friend @ work and it was too much for my stock engine.Did some reading at Holley's web site.Either the carb has a 50cc shot or the jets are for a Boeing 747....It may have something to do with the intake.But til I get the Stealth intake it is sitting on the shelf.I put the stock carb on it and it is running idling and getting up like a CHAMP!.It is idling at 700 and in gear it goes to 500 with out a hitch.

theres probably NOT enough spark since it been changed over to points.I tried that once to a 302 and it didnt work verry well.Put elect.ing back in it and gap the plugs at 45ish and it will handle it providing the jets arent to BIG.I have 76/82 in mine.Mine ran allright on a 260.It also had elect.ing
