I am in the midst of buying the parts for my 351 swap and was wondering what size MAF I require. Im trying to keep the costs as low as possible but If I require something to make it run better I'll get it.

I think the sn95 has a 70mm stock (correct me if Im wrong)
Im either going 351w or 393 (depends on condition of crank, ect. when I tear it apart next week) with afr 185, approx 9.5-10.0:1 cr, intake not decided yet (suggest one if you can). No turbo/charger or nitrous.

Will I need to get a new MAF and TB? Not getting them may solve a few tuning issues Im going to have (need computer tuned before I run it, but want to run engine a bit before I take to dyno tune).

I have been jumping all around on this build trying to decide the matching of parts, but that is all ending this week when I go out and get the parts finally ordered.

I really need some help from the experts here and even some of the other guys too.

Thanks

what ecu are you using?
You may not require a custom tune, but that will depend on the cam, etc.

I would try and get a 70mm MAF, or larger.
24-36lb injectors, depending on the heads and cam... I'm not sure how to figure that though.

I was looking at 36# injectors. I have the afr 185 heads ordered. Just have to wait for 3-4 months they told me to get them in stock.
Im using the stock sn95 ecu and was told that a 70mm (supposidly stock ) is large enough for that application. I am probably going to get a custom cam or talk to someone at a cam store for a good off the shelf cam.
Just trying to not overbuy parts that arent really necessary.

Thanks
