Mopar SB love closer lobe centers than SB Ford and Chevy do I would not put a 110 LSA cam with small duration at .050 like that one is in my car or any motor I put together for anyone I know or do buusiness with

I would not get to wrapped up in advancing that small cam with that many cubes. I'd be tempted to go to the next larger lobes on a 108lsa and stick it in around 104 as it will still make lot's of low end. I ran the 278,251@.050 .608 w 1.6 RR 108lsa 103 icl on a 408 and it was still loaded on the bottom end,ran mid 11's with a 2barrel carb and 2.50 rear gears 28" tires.No cage at the time.

Why a 2 bbl?? Why 2.50 gear??

---

Just to make a 10.50 street car run 11.50's so I could bracket race without getting booted for no roll bar.

How about that for a SB 418 for the street?
the rest of the combo is: Edelbrock heads, air-gap or Xcelerator intake, holley 750 vac-sec, rc 10:1, 4-speed manual and 3.54:1 gears.

---

What choose?

---

The Xcelerator intake if it were mine...

Dont quite get why anyone wants to run that small dual plane on any 400 + cid small block.

---

I see why... its a street car and the low end would
be better... he will most likely never see more than
6000 rpm
