I previously ran a msd 6al with blaster 2 coil on a 468, and I forgot
what spark plugs I used, and it seemed to supply sufficent fire..to
up grade to a 496 blown BB, will this ignition system be good enough,
and also what type spark plug should be used? thank rdobbs
i would talk to the guy that is building the engine :).but i would say a msd al6 is ok but the 6al BTM that is with aboost master will pull timing out as boost go s up keeps the pistons happy.if you going to run it hard . as for the plugs your heads are close chamber rec ports so start with a 396/375 hp or a 454 L s5 plug i think a RN11yc or autolite 64 would be a good place to start
With the blower wouldn't he be better off with a non projected tip plug??
Just curious..........:toocool:
well that is some what of a cold plug .same plug i use in my 548 with 10 pounds of boost on top of a 10to 1 bottom end seams to work fine for a street blower.but pushing more boost or top fuel then no i would not use that plug .75% of the time your not in the boost any ways
Pat, I just printed your reply off for future reference....You are right I should have ask the builder:LOL:....Hey, I sure like those two breathers
on those valve covers..How about a swap:D..rdobbs
well my first bbc had a set like that over 30 years ago it takes abit of work to get them to fit a with roller rockers and a hi lift cam and more mill work for the moon breathers it the only way to go with a blower .i pull one of the plug s that the two blown 502 offshore engines where dyno out with it was one step up hotter then i told you to use them engines were low boost with smaller blowers then what you have but makes over 600 hp on pump fuel so i think your ok .when time comes i will tell you or set up the dist curve and help you tune it inQuote:

Beautiful Pat, one of those looks familuar........Do you think one breather
on each cover is sufficient....what do you think of an evacuation kit?
rdobbs
the evac kit will not work on a car with a EX you better off with the KN breathers or you could do the moon s like i have on mine one on each side :DQuote:

reccomend them or others, and from what you said above it looks
like a pro like you would need to install them, and would they work on
my valve covers...I just like the idea of plenty of breathing.r dobbs
well i used two on each of mine with the 548. i have had breather that did not work good but them moons do a very good job.i do not get any oil on the fire wall or on top of the valve covers with them .i think your covers are at a angle ? on the top .so you may want a breather that s less of a angle .it would be one of them deals were i would need the covers and then go from there . i could look at may breathers to see if the fit would be good on your covers .you could put them on. i needed to do some mill work on mine to fit so it not a big deal for me to put them on .Quote:

covers or other parts, plus I think they look cool:D..........rdobbs
yep you could do them tubes as well like what is on the blower boat engine in photo toQuote:
