SUP. YA'LL.. I was wondering if any body out there has done it yet? I have been thinking of building a 335 with world torquer 305 heads with either the lt4 hotcam or the zz4.. and an aftermarket intake, with the holley 670 cfm tbi... What do ya'll think, any input will be noted.... thanks

 

be cheeper to do a 355 and more tq

 

ya but is a 335 more original plus i already have the 305... i want to be able to tell people they got beat by a 305 lol

 

Search. I say it's a waste of time/money.

 

just get a 350 and tell them they got beat buy a 350. Why spend more money, do more work and make less power just to say they got beat by a smaller engine. You dont want to get stuck at the end saying "i should have just gotten a 350".

 

would the 670 cfm feed a built 350 i.e torquer heads intake, headers,lt4 hotcamor zz4 cam. what kind of horse power could be expected? is the lo5 the best block to use?

670 wont flow much. Keep in mind thats at 3inHg so your talking around 500 cfm in 4 barrel carb terms. Good heads and a full exaust is the way to go but "hot" cams wont fly with tbi. Id suggest considering a milder cam for your setup. As for blocks, id try to get one of the older higher nickel content blocks if your going to do a rebuild. One other thing you could do is to get a short block and add in the parts you want. If you dont mind dealing with a two peice rear seal and a flat tappet cam you can get a new gmgoodwrench 350 short block for around 1k( i bought the complete motor for 1250 but it sucks *** in stock form). If your lazy like me and you just want to plug and chug getting a new/rebuilt shortblock and putting the parts you want on it is the way to go.

 

Not to nitpick, but if you beat them with the 335, you couldn't say they got beat by a 305...i was interested in this swap too, but no one has really tried it yet, and i am working on a suspension right now first.

i am going with the L05 block, LT1 cam, edelbrock performer carb intake bolted to the rest of my mods next summer. The L05 is a good choice because it is a roller block, 1 piece rear main, and late model centerbolt design.

 

From a technical stanpoint I'm not a big fan of the small bore/big stroke engines. This combination of a 3.736" bore and 3.75" stroke is silly for a SBC; a stroke that's longer than the bore.

Try and find a manifold with short enough runners to feed a 335 stroker across the rpm range. I bet it's pretty tough.

 

to me i think that a long stroke /small bore engine is the way to go look at what most of GM's new engines are they are a long stroke/ small bore engine. look at the way the new 5.3 truck engine is put together out powers the old vortec 5.7 and will get better mileage too.

If you don't want to turn a crazy amount of rpm's a long stroke small bore is the way to go.

but if you thrive to turn 8k go with a big bore short stroke and turn it's guts out to make torque on the upper end


IMO i say go with a long stroke small bore turn it till say 5k and make torque and power in between 2-5k if you don't have to turn the hell out of it to make that high duration cam to work if will live longer and get better mileage will making about the same amount of power.

smokey yunik said years ago put the longest rod available in a engine and make everything else work.

with TBI killer HP is hard to get but you can make torque. so with a long rod engine it will make for better torque. cause everybody know that with more rpm's more hp basically.

well if the TBi can't flow the air to make high-end hp. lets build it to make torque .

 

There is at least one guy on here with a camaro that has done the 335 if you do a search on 335's im sure you will find him, and he is very helpful on this topic..

 

Uhm... long ROD and long STROKE are two totally different things. Read what he said, not what you THINK he said.

I couldn't agree more about building a TBI setup for torque. After all, that was the original intent when using TBI. It was made for trucks. Why anyone would want to build up a high RPM, high HP engine with the stock TBI is beyond me.

What GM should have done is put the TPI on trucks (torque monster), and made a 4 bore version of TBI for the cars. It would have made SO MUCH more sense. :lala:

Oh well.
