1600 DP Upgrades for a bus with big nut trans

[Erik G]

So, my DC is getting here soon. It has a good running 1600DP. I want to add a little more power but I know that trans is going to limit me.

I have access to some 40IDF's. I've run 40's on a 1600DP in a squareback with good results, but not in a bus. Dual Carbs do seem to keep it a little cooler, and I like IDF's and DRLA's better than kads. Id rather use Dellorto 36's but the 40 IDF's are available to me.

Anything else I should do? I guess probably ditch the stock exhaust if needed. Would 1.25 rockers make sense to do in a bus with redux boxes? What distributor should I run if I'm doing IDF's, rockers, and exhaust? 010 or 019? or something else?

I usually like to keep it stock, but a little more oomph in a bus is always a good thing, within reason to keep it reliable and cool

Thanks
Erik G

I use a 010 and like it a lot! I am also thinking that adding a nice cam would help.

[Erik G]

yeah thats why I asked about rockers, I'm ok with adding bolt on stuff but not splitting the case on this one. Maybe down the line I'll build something a little bigger, but not for a year or till it breaks


My buddy that grew up in shrevport says there are no VW's down there any more. Is he BS'ing me? My DC was actually sent to NOLA from the factory, might have to take it on a nice drive from Houston

here in shreveport I have never seen another split window bus, have seen bay windows and beetles here and there and I have had ppl tell me that they have seen a red and white splitty in bossier city.
my 67 13 window deluxe was shipped into new orleans aswell!

let me know if you do the rocker arm upgrade I am wondering if that would help my 1641.

If your ever in shreveport pm me.

[Erik G]

anyone else? It's not a stroker but someone has to have some thoughts.

I'm thinking add the 40IDF's, 1.25 rockers, a header and muffler

anyone see issues with running this in an early double cab with late big nut reduction boxes?

Without splitting the case the most you could do is:

The 40IDF carbs they have a vacum port so i would also put a 034 vacum advacne distributor.

Header and exhuaust single quiet pack is perfect

87MM C/P

1.25 Rockers

Oil breather box

If you take the heads off to upgrade the c/p , i would clean the ports on the heads or get some head work done on them.


I had an the exact upgrades but with a 34 pict carb in a 67Westy with bignut tranny. It was a stump puller, one of the best engines i ever had.

Very timely information. I'm in the process of getting a little more out of the same setup here.

I think I'm going to go with Baby Dells or Webers, a Header and 1.4 rockers.

According to my engine guy it should really wake a 1600 up.

Thanks dude. I don't know if there is a vacume port or not, my last set didn't.

I've seen the new slip in 87's Chico is selling. They sound good. I could see those, 1.25's, header, muffler or maybe the vintage speed,, and the heads upgraded to bigger valves.

Just haven't know anyone to actually did that so thanks buddy, hope you are doing well and staying off of bikes or away from cars lol
