Hi all,

iam new to this forum and i live across the pound in holland, europe.
after reading a couple of articles about the bigcads mass torque i was directly interested for one of my street/strip project.
project car : olds 442 1970
already ran 12.57 with a 455 cubic olds without power adder.
suspension all stock.
now i bought me a 472 from 1969 with following numbers and codes:
block 1486238
heads 1486250 (smog rail???)

now my plan is to stroke this 472 (540???). If i want to go this route...this combo must be able to push me into high elevens or mid elevens..

i will change my rearend to a 9 inch and maybe bit narrowed. Olds 442 is a beauty to see. But i want to ran this beauty into 11 with the proper mods on chassis and technique.
I have a 10 inch TCI converter (3000 stall)
TCI Superstreetfighter TH 400
9 inch will be a 3.08 or 3.42 posi...mileage and streetable...

And after good couple of runs and everything holding up, a Procharger to boost more Torque to my GM A body into fast ets......

Budget???

MUST RUN ON PUMPGAS ...................................

Any help is appreciated!!!


Thanks....

Well... first thing I notice is that you have the 6238 block rather than the 5200 block. The 5200 block has a better oiling system, the older block has smaller passages. I personally would try to find a 5200 block.

Good head work and a cam matched to your combination is what makes power, you'll need plenty of airflow to feed 540ci.

My suggestion would be to get ahold of Richard Potter, this sounds like his kind of build. http://www.cadillacperformanceparts.com

ok
smaller oilholes in which hp/torque range would it cause problems?
at this moment i have a 472 and what will it take and survive on the street/strip?
and what would be the best adder for such a big(bad)cad?
lets say rpm 6500......:)

pumpgas rate overhere : 95-98 octane and in germany 100 (v-power)
i am running a plymouth cuda 1970 into the 10.73 on pumpgas.

we are below sealevel.
olds 1970 442 W30.
all stock.

Thanks

I do not see the oilholes being a problem at all.
The oil galleys are big enough in any of the blocks.

You could build that 472 to make more power than you think.

If your interested have someone give you a link to my website and ill help you however I can.
