I have a 2005 LQ9 with 4L65e from a escalade with what I was told only had 58K on it. Im building a 71 C10. Before I install it I wanted to upgrade the cam so I gave texas speed a call. So I have a 228R cam single beehive springs, texas speed push rods and the Yank truck 3000 converter. It was suggested that I go with 243 heads so I got a nice used set. This i was told should get me around 11:1 and be streetable. I have also bought a set of ARP head bolts, ARP cam bolts, ARP balancer bolt, high volume oil pump and a new set of ls7 lifters. Im not building a race car. I just wanted to beef it up a little while I had it out. My questions are with me going to 11:1 will the stock starter be enough or should i upgrade. If so which one? and is there any other weak points for my build or thing else that would help me out?
Thanks in advance

Stock starters are just fine. My car has just a hair over 11:1 and has no problems with the stock 200k mile starter.

 

Thanks for the reply, what about lifter trays or trunion kit? I want to make sure I have everything covered.

 

I would do both.
The modded LQ9 will be a monster compared to any available engine that thing came with,,even the big block.
