Basically here's what I've got: LS1 Hotcam with LS6 springs (all came in kit)

Should I go ahead and get hardened pushrods? 7.400" is the correct length for stock motor?

Would TR-55's be recommended to install while I have everything apart anyways?

The dowel rods you put in the front of the block to keep up the lifters, is it 3/16"?

I think that about covers it. I bought the crane cams spring tool so that should help out a bit. Other than that I think I have all the parts I need. Any comments/suggestions would be great

Thanks in advance,

Jake

 

Do answer your first question: it depends. Pushrod size has no correlation with engine size. It depends on the base circle of your cam. On the cam specs it should say the recommended pushrod length.

Your 3rd question: I believe it's actually 5/16's for the pushrods. The LS1howto should say though.

Your second question: In my opinion, it's not needed. I've been rocking the stock bosch spark plus for 12k after installing my cam and when I checked them yesterday they looks darn near perfect.

 

Thanks for the quick response. I meant to type 5/16" lol, It's too late for me to operate. I'll check the GMPP site again for pushrod length, but do I really need to get new pushrods? I run my motor to 6300 w/out any problems and the new cam doesn't have much lift (.525). I'm not experienced in the valvetrain area so that's why I leave these questions for yall to answer haha.

 

Being a GM cam, it is probably a safe bet that the 7.400 pushrods will work fine. I would throw some hardened ones in there while your at it, just for some insurance.

 

+1 for the hardened pushrods.

 

I'm with them on the hardend pushrods.... It only take one bent one to f-ck things up.

 

+1000 on pushrods

 

looks like I'm ordering pushrods.

thanks for the input, sometimes I have to confirm tha im not crazy ha

install should be soon and dyno at the end of the month. now for 4.10's and 3000 stall coming this spring

btw, will the comp cams magnum pushrods do the job?
