MSD Ignition for the 307 engine

[Broughamfanatic]

I was thinking about purchasing MSD Ignition condenser/cap/coil/rotor wires for the 87 Brougham. Has anyone done the same, or know of any problems I should look out for with MSD stuff? Having more juice flowing to the spark plugs sounds cool, but could there be any consequences?

Yeah, you will spend the time/money to do it and it wont make any difference.

Sorry, I just keep forgetting the best performance mod to the Olds 307 is to remove it!

You all are correct, the MSD won't really help the 307. The stock HEI does an admirable job. Solid for 11s in the 1/4 mile in stock form with stock AC Delco parts.

I hate to say it, but $ per hp, the 307 is hard to build vs starting with a 350 or 403 Olds and go from there. Or even a 400, 455 or 425 makes a nice bolt in too. There were 2 400's, one is undersquare and one is oversquare. Torque output is affected some and what rpm it comes in.

1987 Stock 307, 140 hp/255 lb ft torque VIN Code Y 1985-1990
1984 Stock 307, 180 hp/245 lb ft torque VIN Code 9
1984 Stock 307, 150 hp/255 lb ft torque VIN Code Y
1977 Stock 350, 170 hp/310 lb ft torque VIN Code R
1977 Stock 403, 185 hp@3600 and 320 ft/lbs torque@2200.
1976 Stock 455, 200 hp, around 350-370 lb ft torque.

Now, these are with pathetic lame cams, and terrible restricted heads. It doesn't take a whole lot to make the 350's, 455, and 403's really run good. Even the 307 will respond. But to a lesser extent. The big engines are like a multiplier to mods. And bigger engines have more low end torque, which is what is needed to move our hefty cars along.
