need help with my heads

[swingin71]

hey everyone i was wondering if i could use stock 360 valve springs witha mopar performance .474 lift cam. i am running out of money and wanted to see if that was possible

 

[rumblefish360]

In a word.... NO

 

[swingin71]

haha well thanks i guess that solves that. i will need the MP red springs i assume?

 

[rumblefish360]

IMO, that would be the best bet since there a matched set and set up that way. There not to expensive and will bolt right on without machine work like springs from Comp Cams would need.

I know the "Running outta money deal" just relax and wait, it'll be worth it.

Check the price on those red springs than check out comps springs 901-16 I paid 80 bucks,I have the 474 mopar purple cam in my 360 idles lumpy but pulls real strong.

 

[swingin71]

alright well thanks a lot man

Hey Sanke. What are the MP springs going for these days?
They were allways compareable IIRC and I get great deals directly from my MP parts dealer. Cash is even better. LOL! No taxes. Shhhhhhhhh

I may be wrong but you might have to cut the guide down with that cam

 

[EL5DEMON340]

or at least check it

ok and another thing. i will not be using 2.02 intakes or 1.60 exhausts so my heads wont be flowing as well as i had planned. i bought an MP single plane intake. will that work ok with my heads not flowing as well

With that intake your going to need a stiff gear 3000 stall and your foot into it all day,no good for a stop light to stop light car.The ld340 intake is a good choice.

No clue thatsss why I said check out the prices,however if he can install the MP springs and no machine work involved that's a good deal.For me I sent my heads out for a rebuild and they cut the guide down some and had to adjust the spring heights a tad.I like to avoid the taxessss also LOl.

go with a dual plane intake, comp springs unless you can get a deal on the mp springs.

the mp #847 springs work good and drop right in no machining required.

the comps also drop right on.

About .500 lift is when you need to check retainer/seal/guide contact.
Then consider the 1.45 ratio and actual lift being closer to .440
