engine miss

At full throttle and most notibly in top gear i have a miss. Feels like a reasonably large drop in power (maybe 15-20rwkw). The exhaust note becomes irregular and she generally just doesn't feel as strong. happens mostly from 3000rpm and up. I have the impression it maybe spark and possible related to the warmer weather. Do i need bigger gaps on the plugs for warmer weather? or is there somewhere else i should look?

Any help to diagnose and resolve here would be great.
347 238rwkw untuned and with a couple more lil things to change :)

Re: engine miss

Doesn't sound like spark, unless you have them set too wide and they are being blown out. Maybe close the gaps up a bit and see what happens. Could also be fueling problems, mine did the same sort of thing, missing at full throttle because it was leaning out due to a faulty regualtor/fuel pump.
