My 68 HP 440 has what I believe to be new stock springs, w damper springs in it. It appears to have also had a valve job ( I say appears because I do not know what work was done to it before I bought it but it appears to have been all rebuilt)
My question is:
I am putting a comp cam thumper cam in it.
Specs are:
Gross valve lift I .486 E .473
Lift I 279 E 296
Part number is 279T Thumper series.
I know there is a bazillion opinions on this cam, but I am building a street driver and my wife will be driving it also, so i wanted the sound without the loss of vaccum and drivability. Anyways, I bought the cam and am putting it in.
Do you guys think the stock HP valve springs will work with this cam or do you think I should buy comps springs as well. I know, I know, they are the manufacturer, but some times they just want you to buy their stuff because it is easier than telling you it is okay to use the stock stuff (more money in sales) I really don't want to disturb the valves and heads to do this swap.
Let me have it!! I believe in spending money on parts but sometimes I think ma mopars stuff is just as good as alot of the so called performance parts.
cheers
