Dzien dobry Mizny,
Aluminum 2 bolt caps is the easiest solution I believe?
All 4 bolt caps need a huge amount of machining work to fit...
We have done several stroker motors here in the UK with the 400 and 440 blocks.
Due to excessive 'cap-walk' we converted them with program engineering 4 bolt caps!
The 230 casting is without a doubt the BEST of the stock blocks.
Shorter stroke is always better with longer skirts.
The short skirt engines that we have run on the street with 'pump' gas have all had skirt failures!
Lower compression with shorter stroke is a must for a street engine for me!
I run a 512ci 440-block now with Edelbrock heads on pump gas and she is SWEET!
The best I engine I ever had was a 230 block with a 547 stroker that made 900hp on pump gas!
My 'avatar car' was fastest Euro street car with 8.3o @ 178mph back in the 90's...
Blocks don't last long with over 1000hp lol...
Best wishes from England
