lots of dreaming going on in this thread.
i personally dont like v8's, but whatever you wanna do, go for it i guess.
but, if i was going to do a v8, i would do a toyota or nissan v8. for no other reason then that they sound cooler than gm v8's.

but, im fine with my boring sr, so i dont really care.

 

The Titan motor is awesome. I hope that people really start doing some serious r&d on this motor. There's plenty of room to grow.

The 302 is great on a budget. It would be nice if the block wasn't so weak and ford made a tranny worth having.

 

What ever happened or is happening with your sr tommy? I'll mount an sr over each axel of a 240 to rival your v8.

 

Always about power with you guys lol. I've heard of bending a push rod, lifter failure, rocker arms breaking, etc. You never hear of someone breaking a bucket (sure it's happened somewhere but I've NEVER heard of it). Cam spins, cam rolls over bucket, cam opens valve. LS1, cam spins, cam pushes lifters, lifters push push rod, push rod pushes rocker arm, rocker arm pushes valve, valve opens. It's like saying lets sprint accross a football field but instead of a straight line lets do it in circles. And let's not forget rocker arm geometry lol.

And hey lets upgrade the cam! Remove water pump, remove front cover, remove crank pulley, (depending on car) remove condenser, use special tool so lifters dont fall or just fuck it and hope nothing fucks up, slide cam in and HOPE it wont get scratched. Or hey Stock 1UZFE head flow rates IIRC @ .300'' 240cfm. LS1 stock head @ .300'' 187cfm.

I've driven countless 240's with LS1 swaps, some with built heads/cam, 420+hp, some with cam/headers, and one even automatic LS1 with shift kit. Their bad ass, fun, and hella tq and they got my respect even if i do hate them . But if I had to put a V8 in mine, it wouldn't be an LS1 it would be a 1UZ. Esp when I can buy an entire swap with transmission for 300$

 

SRs have thrown rockers, ate rockers, plenty have spun enough bearings to keep clevite and acl busy for quite a while, however plenty run every day, sure you can put an idiot driver behind the wheel of an LS1 car and tear shit up just the same as an SR20, realistically the whole pushrod thing is a bit silly, especially when the engine you are putting down makes much more power, and has a lot better head flow than the engine you are praising.

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

Ouch.

Also consider this, you'll likely be limited to cams smaller than .511 those 1uz heads did that flow at, and typical LS1 "mild" camshafts run in the .550-.590 lift range, heres the head flow for those same "truck heads" in the lift range that will be used.

.550 251.2 181.2
.600 253.0 184.4

Sorry, but if you really want to worry about yourself screwing up and bending pushrods, thats your deal, but dont preach it as a better engine because millions of pushrod engines go down the road, and drag strip every single day, the Cadillac CTS-V put plenty of hurt on other teams with overhead cams enough that they bitched about it.....

I'll take the highly unlikely possibility I might screw up and bend a pushrod all day for an engine that is smaller, easier to work on, and performs far better.

 

like i said...lt1 ftw

 

While its decent, especially if you can get one for the right price, the LS1 has quite a few reasons its better, however I wouldnt hesitate to use an LT1, if I ever decide to build an S chassis for drift, i'd probably use an LT1 for the build.

 

Like I said before, the pushrod design is just fine. It's been reliable for years. Hondas are some of the most reliable motors built and we still see engine failure with them as well.

The ls1 is a hands down great motor in the small block world.

 

Oil pump bulb end of the pickup fell off, thanks nissan good job on the welding.

After that I did some listing what parts i'd need to make 400 rwhp how i'd like to, and what it would take with an LQ9, factored that in with the cost and hassle of maintaining things with the SR20, and the fact that I had a GTO T56 sitting that cost me $200 and needed ~$200 in parts to fix it, just makes sense, not to mention the better driveability of the larger engine.

Anytime I happen to need a replacement part i'll be able to run to the local parts store and get it, i'll cruise at low rpm, still get about the same fuel mileage and be able to run 10 sec et's on the bottle, win win win

I resent this comment. ha ha ha
