Single Port Performer

[lowbay]

So i recently picked up a '68 ghia for my wife. Currently she drives a 2003 Mitsubishi <sp? eclipse spider gt (v6) anyways she likes the power of that thing alot. i know i will never get that kinda power out of the stock 1500 but i wanna build a fun little motor for her.

The case is a 1500 in perfect shape im gunna bump it up to a 1600, im also going to run a set of dual solex 34mm from cb performance. as for heads, stock single port and internals all will be balanced but stock

heres my question, ive been looking at engle 100 cam and also the 120 any suggestions, other recomendations for cams? im just looking to take her attention away from it not going as fast, but still be a zippy little car thanks!

230-240 deg at .050", that's all you want with a 1600 sp
The engle 120 is way too much!

I built a 1776 sp with a 110 cam out of spare parts just to see what it would do. It was in bone stock bug. That little motor ran really good and made for a great DD. It did run on the warm side with the stock jetting. After re jetting motor ran great. The possibilities are endless. Search for single ports on here to see what others have built.

Right now Im repairing my 1500 SP engine, I am using a Engle 100 with 1.25 ratio rockers and hi-rev single valve spring, retainer and keepers. I am polishing the intake and running dual kadrons. Im expecting this little engine be reliable and torquey for a daily driver. Let you know how it feels whe I get it intalled this week.

Sounds pretty similar to what I'm trying to build. A stock 1600sp with a W100 cam. In my case I'm going for the dual Weber 34 ICT kit from CB (curious to know why you went with Solex carbs? Not suggesting it's a poor choice, just curious to know what swung it for you?). I'll be using a 200mm 6V flywheel, new Mahle 1600 P&Bs, new Mahle lifters, full flow filtering, stock 69mm crank and rotating assembly balanced from gland nut to pulley nut.

010 is far too much for a 1600sp.
019 is a good choice.

To be honest you can get a lot out of a small single port engine. I've got just shy of 80hp on my 1641 single port.

Your splitting the case so here is what I would recommend.
Get a DPR counter weighted crank, they are $175. This will allow you to rev a bit higher to suit her driving needs a little better. It won't kill you if you don't but it would make the bearings last longer.
Engle 100 cam, absolutely. SP's do not like large cams at all. I wouldn't even put a 110 in a single port smaller than a 1776.

If you get a set of ported SP heads you will quickly realize how easy it is to get more power out of them. Brother's can make you a nice set D port and welded with SS valves for about $500 for the pair. WELL worth the money... they will prove to give you the most power out of anything else in your build.

You may even want to consider using thick wall 88mm pistons which would bump you up to 1679cc. They are stock bore at the case and only the heads need to be opened up.

Dual 34's are a good idea as well. If you need the electronic chokes go Kadron or Solex if they offer them, if not grab a set of Weber 34's instead. They will give you more power though do NOT buy the cheap ones, they are absolute junk and you will be replacing them within a year.

This combo properly set up would put you at about 75-85hp which will be plenty for your Ghia and your girl will be very pleased with the power band.

do you want to keep it a single port?or do you want more power and dont want or have to spend $ to buy dual port heads? look in the vintage section there is a lot of single port stuff going on there. if you just want more power and a biger cam go dp. but if you want I need to stay sp , that can be done with out much problems also. check with spencer on the vintage threads.

I have a similar setup to what you want to run. SP 1600 with Kadrons. I run heater boxes and a stock peashooter. I chose a stock cam to go with mine since it's in a 59 Bus. It's a terrific running motor with a very nice powerband. It pulls harder and longer than a stock motor but I don't worry about over-reving it with those tiny little ports. I figure it acts as a governor.

Personally, I'd recommend running a stock cam, especially if you are after torque. Anything else is going to move the powerband up. If you're not diggin' it, you can always use ratio rockers to pop the valves open a bit more.

I'm all for counterweighted cranks and ported heads, but I think you're wasting your money porting single ports and putting a CW crank in a SP motor. It's just not going to see the RPM's that make it a worthwhile investment.

i have a 1776sp in my lowered bus with a 4.12 68 bug trans and 205/60/14 tires.
weber ICT carbs 145/60 jets, SVDA distributor with vacuum to both carbs,
e100 cam with 1.25 rockers on solid shafts,
everythign balanced, stock crank and rods,
1 3/8 header with $20 cherry bomb oval turbo muffler and custom pipe
routing(that made a big improvement from the single quietpac)
cheap empi breather box, heads have valve job, cut back intakes,
cleaned up exhaust ports and single hd spring from lowbugget.
i love how it drives. the only thing i'd change is a 78 c/w crank.

Here ya go.
Single port that runs 11.259's at 120mph quarter mile.

One nice thing about counter weighted crank shafts is the smoothness it provides. Yes in my opinion worth the money.

Thanks for all the info guys! im not lookin to make it run 11's lol i wanna build her something that will keep the hondas in her rearview mirrors from light to light and be able to merge onto the freeway without gettin smashed...

i do want to stick with the sp heads for a few reasons, one i already have them and two im not looking to spend big bucks on the motor... im not going cheap by anymeans i want it to be reliable but i dont need a show piece. i think im gunna stick with the 1600 jug kit and go with the e100 cam, the crank is stock, i took it today to get it ballanced and pollished.
does anyone recomend a shop to get my heads ported? im in AZ thanks again guys

for beating hondas and entering freeway you should at least go up to 1776, since its a ghia you can get away with 1914.
the best would be a 1955, maybe a 2007. if you have to buy a crank
anyway you might as well get a 78 stroker.
with one of those set ups hondas and the freeway wouldnt be a problem.
the 1600 will still struggle some, though the way you are building your's
it'll struggle alot less than stock.
