zeitgeist57 Posted October 27, 2020 Report Share Posted October 27, 2020 The '75 Dodge RV is going under the knife this winter. Wifey-approved for some interior and mechanical upgrades to make it more enjoyable and functional in the coming years. Three big powertrain problems with this thing: 1) oil leaks, 2) R12 A/C needs converted, and the Big 3) The Holley 2245 2bbl carb is a piece of junk. I'm always trying to keep things within a reasonable budget, but this long-term family hauler is OK for some $$ upgrades if it makes sense. I am going to have to install a new fuel tank to get better range, and if I'm going to make a carb-to-EFI conversion I want to decide that beforehand in case the new tank needs fuel-return provisions, in-tank fuel pump, etc... 1) Keep the 2BBL + cheapest, easiest mod. Just get a more common Holley 2300 or similar, no fuel mods, throttle mods, etc. - Low HP, no towing/elevation improvement if we get a tow-behind or go out West (both conversations we're having) 2) Go 4BBL carb + Solves drivability issues over 2BBL, Boost in power (40hp) with not a lot of other mods. - Fuel economy, big step-up in cost, full intake changes 3) Go EFI + Best drivability/efficiency improvement, should be ideal power relative to air-fuel ratio. - cost,cost,cost...and maximum modifications (engine intake, fuel lines, tank, wiring, etc) I had a 1st-gen Holley ProJection EFI that I sold, as the P.O. had it on the RV back in the '90s for less than a year and went back to carb. This is not a classic musclecar; i'm not driving it often and I don't know if the cost for EFI is worth it. If I can get a good Edelbrock or Holley 4BBL carb/intake setup for less than $600-700, that definitely seems to make the most sense to solve 2BBL issues and add power. To put away the nuclear option: the 360 runs really well and the P.O. put some good work into it over the years, including long-tubes. An engine swap is out of the question for this stage of ownership. :gabe: Just curious if anyone out there is swearing by the Holley EFI or FITech systems over carbs for a weekend cruiser enough to recommend them. We've certainly gotten to a great place in the aftermarket where EFI and max tunability can be had for less than $1500. Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted October 27, 2020 Report Share Posted October 27, 2020 Curious how big of a pita is pulling the engine ?? If factoring long term ownership vs cost to do so I would pull the engine , get all the oil leaks fixed up and go efi for long term mpg and power Quote Link to comment Share on other sites More sharing options...
cruizin01 Posted October 27, 2020 Report Share Posted October 27, 2020 I would only consider a Holley Sniper if I was in your shoes and wanted to put some money into it. You could even do the 2300 2 barrel kit. A basic in tank pump with a return is what I would recommend since your doing a tank anyway. With that said you'll have to put a little effort into setting it up correctly. Its not a plug it in and go system as it claims. I learned everything on my own on how to tune my BBC with sniper and now with the Terminator LS setup. The software is pretty user friendly imo.

Cordell Posted October 27, 2020 Report Share Posted October 27, 2020 I would go EFI hands down. If you do everything right with a carb then it’ll be good most of the time, but do everything right with EFI and it’ll be good all of the time. From a tuning standpoint Fitech sucks, there is no resolution to the tables in the tune, this may work ok since it’s not a modified hotrod, but I don’t like it. Holley is becoming the industry standard in aftermarket EFI for a reason. Besides there is alot of people playing with the Holley stuff out there so I think support would be better. Get a 4 barrel Holley setup, get over the cost, make sure it’s installed right, make sure the exhaust isn’t going to leak (so the O2 works right), and when you get into some hills or tow something It’ll just chug along. Profit. Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted October 27, 2020 Report Share Posted October 27, 2020 Please excuse my ignorance of carbs, I can't find comparisons of the 2245 VS 2300. Can you not do the Holley Snipper 2300 with your intake manifold? I assume the 2245 and 2300 intake flange is the same from your original post talking about upgrading to the 2300 and not needing a new intake.

zeitgeist57 Posted October 27, 2020 Author Report Share Posted October 27, 2020 Thanks for the quick responses, guys! https://www.speedwaymotors.com/shop/holley-sniper-chrysler-small-block-v8~131073-11665-9 Is there a distributor option that's worth waiting for, like the SBC/BBC kits? Kinda sucks to spend $1300+$400 for an Edelbrock Performer RPM manifold and still have the factory dizzy. Quote Link to comment Share on other sites More sharing options...

Kinda sucks to spend $1300+$400 for an Edelbrock Performer RPM manifold and still have the factory dizzy. The option I like for Mopars, is putting a the Pertronix dizzy in with the Ignitor III module already installed. Or just put a Ignitor III module in your existing distributor. I've done both and would recommend either or. Quote Link to comment Share on other sites More sharing options...
TimTaylor751647545500 Posted October 27, 2020 Report Share Posted October 27, 2020 I've been kicking around the idea of upgrading the 442 to the Holley Sniper setup as well. Seems to be the go-to. Quote Link to comment Share on other sites More sharing options...
cruizin01 Posted October 27, 2020 Report Share Posted October 27, 2020 I installed the matching Hyperspark distributor in the BBC after doing the initial Sniper install. I noticed next to no improvement in performance and/or drivability. I wouldn't spend the money on that again for your setup. Just get something reliable whether that's OEM or normal aftermarket dizzy stuff. Quote Link to comment Share on other sites More sharing options...

The factory '75 dizzy is already inductive pickup...I guess that should work as long as the Mopar ignition modules hold up. Quote Link to comment Share on other sites More sharing options...

Then an Ignitor III would still be an upgrade. It retards timing to start, multi-spark through the whole range, and has a built in rev limiter. It's like having an MSD box without the extra box. My suggestion will probably be the least loved option. Get the edelbrock performer spread-bore intake and put a well sorted quadrajet on it.

Geeesammy Posted October 28, 2020 Report Share Posted October 28, 2020 EFI or the 2300 option. The "older" I get the less I like half steps. Just do it right or dont do it. Quote Link to comment Share on other sites More sharing options...
