I have a regular HEi distributor with an accel super coil and cap with a set of 8.5 mm quality wires, and my plugs are + 4 bosch platinums....my question is if I up grade the module to a performance one from P.A.W. or Jegs will I notice any difference , (benefit) over the stock module and is it possible to gap the + 4 design or just run them the way they come....and what is everyones opinion of these plugs?? THX Mike
 
maybe it's crazy...but the guy who rebuilt my 350 sb recommended motorcraft plugs for my engine. he says that is what him and his friends run in their drag cars. anyone heard of this/

Most overheard question in the Carolinas...................."Randy who"????
 
I'm running an MDS 6a, and Mike recommended a gap of .6 so that is what I am running! (with NGK plugs...)

I have been told by people who have bought the Hi perf modules that they work better at high RPMs than the stock module. They said they didnot notice any difference at lower RPMs. The stock HEI starts to crap out above 4800 RPM. The Hi perf module allows operation at higer RPMs.
AS for the Bosch plugs I dont like Bocsh platinum plugs. I have had troubles with them In VWs and domestic V8s and dont think they are worth the money. Also the +4s cannot be gapped.
I run Motorcraft plugs and like them. Most of my buddys who race use them. They are cheap and they work good and last a long time. I also like and use NGK plugs.

I don't know if the can be gapped, but I can tell you that everybody I know of that know's a lot about engines etc. do not like the bosch plats.

THX SOLO for the replies and yeah I have heard split decisions and so I am trying them.....no difference yet......normally I run NGK in my truck and all my sleds..probly go back to them and get the 56.00 refund for not being satisfied with bosch, THX again
 
No, the +4 plugs cannot be gapped.

actually what everybody tells me isn't that they 'hate' the plugs, but that they wear out as quickly... moral to the story; you spend a lot more for a plug that doesn't perform any better.

I have all MSD stuff and run either NGK or Ac Delco plugs gapped at .060. Seems to work well. I'm not a very big fan of Bosch stuff. Only car I'd ever stick it on is a VW cause that is what the factory uses, but overall Ithink those plugs are kinda junk.

I talked to a guy at a local parts store in Phoenix, and he told me that every set of the Bosch 4+ plugs he sold to anyone with a SBC came back fouled. I run Champion Truck plugs with my MSD gapped to .057. The plugs a good plugs that have lasted me a long time. Every once in a while I take them out, clean them, regap them, and stick them right back in. The truck plugs have worked well for me, and I use them in my truck, and my dad's 2 trucks.
