Stock 427

Hi

Short question, what 'things' did a stock (yenko) 427 have ?
Like what cam, what headers,...etc ?
Or can someone give me a link to a site where all of this is written ?

Thanks !

4 bolt main thick wall block.cross drilled nitrided steel crank.heavy duty "dimple" rods with 7/16 bolts.Forged pistons.rectangular port heads with 2.19/1.88" and 11: compression ratio .Solid lifter cam with .540 intake and .560 lift,alumium intake and 780cfm carb.This engine ran best when shifted at about 6800rpm.with headers and a good tune up it made about 520 hp at about 6600rpm.

Re: stock 427

Feel free to add me as a friend.There are guys here who would know more specifics about exactly which cam or heads that were used at certain given production dates then me,but his was a general guideline.The 427's in the COPO 69's were bone stock except for the headers and,tune and some bolt on items.Exactly what was done to the conversion cars I dont know.To put it into perscive the L72 long block including the stock cam was a very potent combination,and was used as the foundation for many drag race enine buildups for decades after i was taken out of producton.It as more mild mannered then the L-88 or LS-7,but stronger then the LS-6 in drag car.I run low 10's in a 3500# car with an 11:1 .060 over 427,with a stock GM .560 cam(A sligtht variation on the L-88 cm}with bowl blended stock size valve L-88 heads{new GM replacement) a single plane intake 850 carb,and 2" headers,all stock suspention and 10" tires.I ran 10.60's with bowl lended stock iron heads,so there isntmuch difference ohter then the weight.
The stock GM stuff as well as simlar parts can make a lot of power for low cash.

Thanks for all of this, I really am eager to know everything about it !
And I'm sure if a 427-guy reads this and he is willing to say something, he'll tell me which cam, headers and so on ;-)
Everything you're saying is getting less and less Chinese to me, I you know what I mean !

Thanks pal !
