LS1 wasnt mentioned till you brought it up:

Come on you can make shits loads of power on stock cams you just need a BIG turbo. Ppl have made 650 on stock bottom end. Im worried because im running 26psi on my DD with stock bottom end but even then I have a awesome tune so im not that worried.

 

If you want to be like that I should just quote the first thing you have ever said on tr about v8's.

 

ibtl

 

But at that point (stock cams with a huge turbo) the powerband is going to be shitty, again, i'm building a daily driver, not a dyno driver. I should have about 400 + ft lbs from something like 2500-6000, it will drive much better around town than a large turbo on an SR, I never said the power cant be made on an SR, but overall, for what I want to do, which is have 400+ rwhp and daily drive it, reliably, my choice meets the requirements, and does so very well.

Add to this in a year or two I plan to swap the longblock for yet a different truck one, using the same cam, at that point it should make 460 or so rwhp, and lose 70 lbs due to that one being aluminum block, couple that with a 150 HP nitrous shot, and it will be a reasonably quick daily driver. This again all on a stock set of unported heads and a mild camshaft.

 

Yeah and those stock ported heads are on a 1300hp car running 6's. The entire engine set it's self costs 500-300$ compared to your XXXX LS1 swap. I dont want 400tq @ 1000rpms in my 240, I want that in my truck or non existent gay drag car. My argument wasant even with LSwtfever it was OHC being better then OHV and they are as I stated in shrouding effect against you're "OMG I can run huge ass lifts on my engine" it's because it's a fucking OHV, OHC can run efficiently the same as a OHV at half lift because of less shrouding. OHC - less shrouding - less lift - not as much stress on valve springs, i'll stick with my OHC, easier to work on, less lift, less tq, bucket/shims, etc etc. There are plenty of bellhousing adapters cheap for pretty much any transmission you want. Go through that V8 thread again.

I'll stick with my OHC $300 engine you keep swinging GM's nuts.

 

You do realize that those 1UZ heads didnt flow as much at the low lift values either right ?

Keep on not comprehending when you are wrong, its amusing.

To recap:

Specifically on the 1UZ that you want to use as your point of reference i'd like to see where you got those numbers, here are the only numbers i've been able to find for those heads. At 28"
Lift Intake Exhaust
.275 203cfm 125cfm
.511 230cfm 150cfm
Compare those to the stock 317 "truck" heads on my engine
.300 204cfm 146.8cfm
.500 250cfm 174.2cfm


Once again my stock truck heads flowing the same on the intake side at low lift, along with more on the exhaust side, and at a LOW .500 lift, flowing 20 cfm more intake, and nearly 25 cfm more exhaust.

Like I said before, all you are doing is crying "wahhh, ohc is better, cause well i say so, it doesnt matter if it makes less power, takes up more space, and flows less air, its betterrrr waaahhh"

Good they have made 1300 HP, with 60 psi ?

The same HP numbers with higher torque numbers have been done on turbo LSx's, you do realize that your precious import engines arent the only things around running turbos, right ?

Good you stick to your $300 ohc engine, with its whopping 261 HP, or 291HP if vvti, and god like 267, or 300 ft lbs, i'll keep my "gm nut swinging" truck engine with its measly 345 HP and 380 ft lbs, stock, with its heads that you cant seem to grasp the fact that they outflow your precious ohc engine.

 

You are probably going to come back and still not admit you are wrong, but heres more factual data you can try to argue with, found another flowbench test of a 1UZ head:

Browser Warning

Lift Intake CFM Exhaust CFM
.100 51 36.3
.150 77.1 57.2
.200 96 66.4
.250 113 74.1
.300 121 81.7
.350 124 86.9

Again the stock truck heads on my engine

.100 64.8 53.3
.200 142.1 111.6
.300 204.3 146.8

Again, things dont look too great for your OHC vs pushrods claims, your other list is bullshit too, but I wont go further into it, good your engine cost less than mine, mine also makes more power, is more compact, and has a greater power potential, worth the few hundred $$ extra to me

 

Moral of the story, sorry your 1UZ heads dont flow anything special at low lift, and with some actual lift, where my heads will actually be, flow a huge amount more, the fact is you cant make similar HP numbers on a 1UZ without boost, add to that the engine is larger, package that with a forced induction setup and you get a cluttered engine bay, real fast.

Its cool if you dont want to run an LS1, I really dont give a shit, but at least admit you are wrong when you try to justify choosing a less capable engine and get proven wrong.

 

Oh, how bout the stock truck L92 heads vs your precious 1UZ flow numbers, even using the higher figures we were going by before which were :

.275 Lift 203/125 vs the L92s 212/162 @ .300
Thats pretty harsh, especially on the exhaust side, your 1uz heads are looking pretty sad for being such a badass ohc head vs a pushrod truck cylinder head...

.511 230/150 on the 1UZ Vs the L92 @.500 302/ 205, seriously if you try to argue this point anymore, I dont know what foot your gonna try to stand on, because they've both been swept from under you.
