interesting....

what would you think about 355 cfm's on intake from a cast-iron head?
and 245 on exhaust side?-all this from a cast-iron head ? and head flows water?
and ports are raised?
Raising ports is key and ONLY way to get BIG flow numbers from these heads-MANY have done it -including myself....

and as far as a main girdle, what do you think about either using/adding 3 "blocks" to mains 5,6, and 7?...
0r a full Block girdle to block?
Know how much these blocks flex?
know what happens with a balncer on front and weight on end of crank does to main bearings 4 and 5?
mmmm, so what does happen at 8000-9000 rpms to block and crank?

Its amazing what many have done with these heads and blocks-yes cast heads and blocks....

Mighty, ask Mike Kirby what he knows about Chevy 250 drag racer in Va(where I am from), and what he knows about the high flow numbers I refer to....(from above)

Seems ONLY way to get big flow numbers in these heads is to RAISE ports- look at Mike Kirby's new aluminum head? Look at a PES fully modified head?

and yes, I bought that busted Kirby head to see what all the "Mystic" is about his procedure....
Well, I was NOT impressed at all- Seems I was laughed at here by Twisted 6 and GMdad for buying junk-seems you missed the point- I know PES technology, and have seen Kirby technology-which to you think works best?
Seems PES learned a LONG time ago to raise ports on these cast heads....

so here is what you do-use a cast head, raise port with CAST welding(if you are not familar with what can be done now with new technology on cast iron heads,blocks and cranks it may BENEFIT you)-and i mean RAISE ports!!!

But then again , I have been mistreated SO BADLY here from MANY -seems VERY few here have even built a engine with a Lump Port head- so what can you say?
I thought those that really want to know what is really going on out there would want to know...
I am not trying to bash ANYONE( as rules state) but I a have been BASHED a long time here

you dont have to like me-its OKKKKKK
but find out the truth about what can be done, what has been done and what is VERY amazing....
but then why take anything I have to say as helping....
so is this Post going to stay as is or be edited?

you should at least let many read it- if you want to question me go ahead, but start somewhere else 1st.....
