I think I have decided on everything...

SSHT 228/232 111 LSA
PRC ls6 stg 2.5 heads, 2.02/1.57, 64cc, .650 dual springs
Ls2 timing set
Ls6 ported oil pump
Ls7 lifters
25% UDP
Bosch 30# red tops

My current mods are slp lid, pacesetter LTs 1 7/8, 3" OR Y pipe, and slp lm1. Car is m6. Sound like a decent build? I'm still not sure about pushrods though. 7.4 seems to be the going number. Also flycutting has me nervous... will it be likely I will need to with a smaller cam like this?

Sorry forgot car is 02 ws6 and came with ls6 intake.

TSP's 233/239 cam can fit unmilled 5.3 heads without flycutting, so I'd seriously doubt with unmilled LS6's you'll have any issues. Talk to Ed Curtis as that cam grind is his, and he'll know what it will clear for sure if you can find out what the valve drop is.

Otherwise, that's pretty solid looking combo. The HT Streetsweeper is a great street cam and very popular with the GTO crowd. Get it tuned well cause it'll be choppy with that 111LSA though.

So can I get away with just swapping to the ls2 chain? Also read a little about comp trunion. This worth while or needed? And is there a gasket set out there I can buy that will cover it all? I was thinking about basic head/cam swap kit from TSP.

I'm not sure you can get red-top injectors now, Ford replaced that part with a newer design that is all red and is skinny.

Ones I found were reman for 110 shipped.

I've wanted to do the same type of build I'm a big fan of the SSHT in most combinations. That should fit fine in moderately milled and unmilled 243 applications. Interested in seeing your results looks like a good combo

Not that you want to, but you should be able to get .240s duration on stock ls6 heads without fly-cutting. Good luck, should be a quick car. This is DD or just a play car?

indigows6

Yea I'm eager for it too. It depends on my mood as to what the car is but mostly a toy. Wanna go to the track every now and then too. Mostly street though but not every day. Heard good things about this cam putting down good power and still being very streetable. It sounds badass too.

mill the heads a bit its cheap power and torque. 228-232 cams are great! I just finished my build with a similar cam 228-232 .612/.612 113lsa. drives great makes great power everywhere.

indigows6

prc 2.5 ls6 heads from tsp say milled to your chioce. guess ill ask ed how much to mill the heads if any then order them. how do i go about contacting him? is his email listed on new eras site?

Milling decision is based on your desired combustion chamber size, which is determined by your desired static compression ratio.

It's a big decision so do some research. More compression yields more power, but like everything else it's a compromise.

Most end up in the 10.x range, but toward the higher end you'll likely be stuck running 93 octane gas for life.

garygnu

get a ported TB.ask what head gasket to use for you combo.

indigows6

^^this was another concern, thanks man. Running 93 doesn't bother me at all.

I'm running 59cc tfs 220's with mild port work. I barely cleared ion the intake side but plenty on the exhaust. I'm on 91oct Socal with no problems even at 100*. Charlie at RPM motors is the man and the tune is spot on. I would find out how far you can mill with those heads with that cam. I would say 61cc would most likely be what you could go with and have good PTV. But talk to the experts and get there opinion, and measure no matter what when putting together just in case! The added compression makes the motor more snappy and responsive. You will love the combo good power and broad torque curve!

This was on 91oct threw not the best headers/ cats. Safe tune and a load bearing dyno not a dyno jet. I'll be throwing it back onto another dyno to get two readings in a week. But OP great little combo that will run hard and be super fun on the streets!

Also if your going to mill don't get the pushrods till you measure for them. If you don't mill I think you want 7.425 not 7.4. No fly cutting needed on this combo unless you mill down to 59cc then you will deff be in the flycutting range. I had enough PTV at 59cc with my heads but with your heads I think 61cc-62cc would be safer with a stock MLS gasket. TSP should be able to give you more knowledge on that.

indigows6

Awesome. yea if i can get more out of the heads for the same price thats definitely a must.

I am ready to order some of the supporting mods (timing chain, oil pump, injectors, etc.) and i was wondering if i can just get the ls2 chain from tsp without buying the whole timing set. Also, does the melling high pressure oil pump perform the same as a ported ls6 pump? I would rather go with the one where i dont have to deal with clearance issues. I have searched for this and couldnt find clear answers. Maybe I had a stupid moment idk haha

I had to get a lower cam gear so my tuner/installer could retard the cam from a +4 to a +1 but if you are installing the cam strait up dot to dot. I think you are fine with just the timing chain as you wont have to degree the cam. As for the oil pump i have a stock ls6 replacement and have more then ample oil pressure!

indigows6

Yea I saw the stock replacement ls6 on NEP. Good price. So I shouldn't have to degree the cam? I just see where many say "ls2 chain" as part of their mods and wasn't sure if that was right for me.

I will say ditch the lm1, lol I had one on my car after the ms4 it was just awful,got tsp duals now with sweetthunders and sounds by far better than any of the exhaust set ups I have had. Its loud but sounds great ,lm1 is just loud. Good luck with the build
