So I got the 650 CFM version, installed it and it fired right up. It's actually a pretty nice carb with screw in air bleeds and 4 corner idle. Took the truck for a short ride and holy crap, it really woke the truck up. I'm very happy with that. It needs a little tuning as I'm getting a single pop back through the carb at WOT under load in 4th gear. I'll try increasing the secondary squirter size first and see how that goes. Overall I'm pretty happy with it right now.

I may try a 50cc pump first and keep the squirter nozzle the same size just to get past that.

The guys that own FST are the same guys that owned Quick Fuel carbs and they then sold the Quick Fuel to Holley. I guess the reason they are making the carbs affordable is it’s a new company and demand has been through the roof. I heard they are nice pieces though.

It is a very nice piece I must say. I had the opportunity to take the truck out for a good long drive yesterday and it is a little lean for my combo. As soon as my ribs heal and the weather permits I'll pull it off and do a little rejetting. Probably go up 1 size on the primary and 2 on the secondary.

I guess the reason they are making the carbs affordable is it’s a new company and demand has been through the roof. I heard they are nice pieces though. No. Marvin Benoit owned Quick Fuel, and sold to Holley. Ken Farrell who started FI Tech also started FST, with some help from Marvin's brother Jacques. Also Scooter Vester worked at Quick Fuel, now at FST.

Get a wideband on that and know for sure whats up. May just need a smaller HS bleed or an easier mixture screw adjustment. That would be too easy.

You can't go too much on the mixture screws. The idle bets way fat and then other issues develop. I went up one jet size on the primary and two on the secondary. It is near perfect. I will step up the secondary pump squirter a bit. If that doesn't do it I'll step up one more jet size on the secondary and then back the squirter back down. I'm not going to buy a wide band for this truck, it's not that critical.

Yep, and their parts ARE from China no matter what others have stated how else can you get a carb for $500 ......

I need to raise my prices then being BLP is USA made minus fuel bowls but they're working on some soon and I get to check the first ones out which is super cool and I'm not bagging just stating facts about where the parts come from. I know many happy customers of over seas products including myself and many on here.....

So just an update, I went up 2 sizes on the primary and 3 on the secondary. I ended up converting the carb to a vacuum secondary. There is just to wide of a gear spread on the NP 435 to keep the RPM up between shifts. The carb is a really nice piece for the price $300, and it runs very good now. Woke my combo right up. Great throttle response as well, so I'm happy with it. I've had to adjust my thinking from making the most WOT power to making low end torque and throttle response.
