2270 Build, Need advise Options

[pilothyer]

I am interested in building a 2270 engine. From what I can see I will need a stroker crank with a 78 mm throw. I am concerned about which rod to choose. I have seen stroker cranks with VW type 1 journals as well as 2.0 liter and chevy. I have noticed variations in rod lengths as well. I am in need of some advise on a good, proven combination. I know there are many good engine builders on his forum that could share their knowledge on this subject so please do...............Thanks

Here's the 2.6L MassIVe engine thats in my 356. It has LE 220 heads, 10:1, roller camshaft/ lifters and lots of other tricks. It optimized fairly well with the 52mm Bologna IDAs pictured, with a 40mm venturi. it made more power on the dyno with 45mm Dellortos with a 42mm venturi.

That said, these carbs will not be on the car for that long, because like all IDAs, even with a 3rd progression hole they lack serious drivability.

I've had these carbs for over 25 years, and I wanted to use them for the 356, but I am seriously not about bling, and much prefer the Dells.

I've only had one T4 like an IDA better than an IDF or DRLA, that was the 3 liter twin plug roller engine in Beth's vert that made 250HP on 89 octane fuel, using these same 52mm IDAs.

I can't sleep well at night if something isn't optimized, I don't give a damn about bling.
