re-planning my lq4 build YET AGAIN. (Build Finished pics and idle clip inside!)
So I was pulling the stock cam out yesterday, when suddenly it just out of nowhere stops being easy to pull. The last lobe where the cam timing sensor reads had a really nasty score mark on it. So now I'm gonna have to replace the cam bearings since I suspect they aren't in good shape.(pulling cam out was a PITA, I've done many cam swaps in the past and this is the first time I've had the cam come out screwed up like that) And if I go ahead and do that. I might as well rebuild the 89k mile block.. im thinking 370 with flat tops. But the problem is finding a good setup. I already have my minor ported 243 heads and PRC duals so now I have to choose a good flat top piston and another cam.. I was planning on 227/235 lsr cam but since the build is taking another direction I have to re-plan everything. So. Any suggestions?
PS. Sorry for the long paragraph. Im on my phone lol

heres when we found out the cam wasn't going to come out so easily.. LOL
And these are the 243's im wanting to use on the 370
just your basic valve cut,pocket work,and bowl blending with TSP prc dual spring kit

We have a new line-up of camshafts that would work very well in your build.

sorry to hear your troubles with removing the cam, at least your new build will be the upside!
for future reference, with the engine on the stand there was likely some extremely minor "sag" in the block (from being only supported on one end) which did not allow the cam to come out. This happened to me on my LM7 block. When I was removing the factory cam (with engine on a stand) the cam got stuck half-way out and would not come out further. On a hunch, I flipped the engine 180-deg and waited 5-min. The cam came out easily after that.

If you have a friend or engine hoist handy tipping the engine back and basically standing it on the bellhousing end is a nice way to R&R a cam, obviously have to be careful as the stand it not meant to balance sitting on the ground sideways like that but this way you can make the cam straight vertical which can help too rather than trying to use some bolts on the end for leverage to support the other end.
A friend recommended this after watching me wipe a cam bearing pulling the cam on my LT1.

Went with Tick's Stage 2 cam on the 370!
the block ended up being a 2003 lq4 which caused me to do 2 30mile trips to my performance parts distributor! blah.
here's some pics of the progress..
hovercar!
Out the top! took me literally 45 minutes (i always take the tranny out first)
then night i got the short block back... +5 chihuahua power!
-4cc Mahle forged pistons
ls2 chain, melling high volume oil pump and heads installed with ARP headbolts \m/
the motor will see some abuse, i like to push things hard so ARP bottom end FTW!
I feel like i've come a LONG way since i built my LS swapped truck.. i look back now and realize this was my biggest project to date..how hard i pushed myself working two jobs while going to college at the same time to satisfy this addiction that runs in my family. I feel blessed to have gained so much knowledge over the past years..junkyard motor with milled 243's and TBSS intake with a circle D 3200 stall on 4.10's that ran high 12's all motor.. i spent 3 years working on the truck. In those 3 years since i was 16 i learned a vast amount of information about LS engines, hell i even taught my Father a thing or two about them more than once. I've been messing around with HP tuners for a while now, i still don't trust myself to tune it hence why i only have VCM scanner lol!

lol, both were a spur of the moment pictures
I'm going back to the dyno soon to get some numbers and see what this cam does on 4in+ bores with cathedral heads. once i pay off my other priorities i'll be saving for an aftermarket rectangle port head and intake setup with another one of your cams. i plan to run 10's on motor next year if not sooner (while sporting a new rear end of course lmao)

Yes I was going to do a mock up of My LM7 .030" over 331ci and with the crank and the old in good shape bearings ,,,,,,,,,,crank would'nt spin ,,,and I remember this engine spinning easily when I was disassembling it ,,,,,so I did something similar and it was all good ,,,,,,but had been thinkin about it 4 a while and decided to fab an adjustable support 4 the end of the block for just such reasons . it works well .

It looked like in the pic of the stuck cam, that you still had your lifters in the motor while you were pulling then cam out...at least I can see the lifter trays are still there...i'd say you started pulling it out and a lifter drop down and the cam got hung up on it...

I'm pretty sure it will make 440rwhp-450/400-410rwtq if it's on a Dyno Jet.
