I just read on Hughes performance that the M1 intake converts the magnum to a 4 bbl. Now this may sound stupid but isn't that a carb.? or is there a 4 bbl throttle body?
Also what do you all think about the m1 intake? Does it help any? and is it taller than the stock intake manifold because I can barely get my Mopar performance air cleaner on with the normal intake manifold?
any suggestions on heads?
how about headers?
Thanks.

 

the intake is the same size it just has a air gap in it and they do make 4bbl tb's and i run pacesetter headers and i bought them under summit headers and it was only 150 for them i also believe the intake does work and is worth it and i am also looking for heads so i cant help you there

 

I was also looking to get a fastman throttle body, would it work well with a new intake?

 

Yes the M1 is a great intake but Hughes is working with edelbrock and making there airgap intake a bolt on item for our motors which flows alot better than the M1so im holding out for one...now as far as the M1 there is a 2bbl and 4 bbl you want the 2bbl version...and it is stock height....52mm throttle is a deff. compliment to the M1 or stocker...

now getting into heads There Heavy duty magnum Heads are a great deal and flow excellent you can pick up a pair ported and polished with 2.02's for 1200.00 thats a steal and they flow so much better than the R/T heads...

and for headers a pair of mid length headers is a good choice like edelbrock ti techs or PPH's or if you want run the pacesetter long tubes any of them are a good choice...
