hi guys i have a 400ci block i am looking at but can anyone confirm it is a 400ci as i can't find these casting number in the picture any where? any help would be much appreciated..looks to be 3830830-400-7 but i can't find any 400 block number that match that casting

.

 

Looks to be a 400 with a date code 1974....

 

hi there yeah after some more research what i found was some of the road runners in that year had come out with the 400 option which i didn't know, do you know if that model had the reinforced webbing?, the guy who has it wants $1620usd for it .thanks again.

 

That i dont know..... I dont think its worth that amount ether. But then again, that may include shipping to New Zealand????

 

hi again yeah i read an article about the road runner coming out with a 400ci and also a 318-340 & 360 but i still can't confirm or find that casting code any where,i found a good little read below in the link. the guy selling the 400 is in n.z i put it in Usd so you could see the price..so its $2500nzd which is a lot.. no i don't think its worth that at all..> he claims its a special block but i don't even think it would have the grunty web in it as i thought the reinforced web only came out in the 400 casting 3614230, everything is a lot harder to get here as we are so far away which makes it hard.. but we get there. i,m going to keep searching and try find that date code let me know if you come across it.. would be good to confirm what it came out of .cheers

Wow, In looking not very many casting numbers to choose from.... Kind of hard to make out the numbers from the photo... Lets make sure i see this correctly? #'s 3680830 ?
We know its a 400 Cubic Inch by the casting and we can see it is a 1974 year... But i am having a little tough time with the full casting number!!!

 

hi there yeah its a tuffy i can't match it up so far with anything even if i try swap up the numbers, i asked if they could confirm the numbers for me but got no response. to me it looks like it could read 3980830 - 3630830 - 3830830 - what about 8830830 - 8630830 -3680830 - ? i,m not sure i still can't match it up

 

really it should be this number 3698630 400 B 1973-78..but its not hat one..

 

Guess we will wait and see if he gets back to you?

 

hey there have you ever use F911 For head bolts?.cheers
