Whats the cheapest way to get 300hp at the crank out of a 350

 

Shorty headers, k&n air filter, crane 2032 cam, tuned prom, ported you runners, remove air

 

Good heads (NOT 70s smoggers)

 

64 cc heads, headers, high flow exhaust set up. Toss the smog bs. Then if tpi, tune your prom to match

 

What are the suggestions for a good set of inexpensive aluminium heads for a 350 TPI?

 

Late aluminum L98 heads with the d port exhaust (113s), also come on the zz4 crate engine, can be found cheap some times. Other times they're outrageously high for what they are. GM claims they'll support 350 hp. They're either 58 ccs or 64 I don't remember atm. Sure there's way better aaftermarket out there but I've seen a set or two sell extremely cheap. Search ebay, craigslist, classifieds, etc. you may find something way better.

 

Full bolt ons will put you near 260whp which is close to 300 crank hp. LT1 auto's rated at 300 hp dyno 260whp or about that

 

How about these heads? http://desmoines.craigslist.org/pts/2629347969.html

 

Well you should google them yourself if you really want to know about them... but hey im bored out of my friggin mind so I did a little research for you. From the very little I read theyre mainly for smaller sbcs (305s 327 etc) and don't flow enough for a mild 350, unless you're looking for loads of low end torque, which your l98 already has. Having such small chambers you'd probably need to get dished pistons if you'd wanna run off pump gas.

Id say no but its your own car and your needs are specific. Can't ask people on here what's best really bc one person will give advice on a torquey motor, somebody else insisting on a high end screamer. Then you'll have the guy who's cheap for the sake of being cheap, or somebody who has more money than the rest of us put together and will talk about how the only parts you should get are the ones you can't afford. I guess what I was trying to say before my rant tho was you should take a long time to decide exactly what you want before you buy anything, or you'll end uplike me nd spend way to much money and decide you're going another route

 

Couple of the things here. It isn't an l98 it's a goodwrench crate 350 with like 190hp stock. I have it torn down right now and it has dished pistons already. So would those be good heads?

 

Cheapest? Nitrous.

 

we have a winner

 

Put iron L98 heads on it and possiblly shave the heads down to keep compression up if those pistons are deep dished. Put a slightly bigger cam in it. Is that a roller block or flat tappet? If flat tappet, then just put in a little bigger cam and run good oil for flat tappet cams. (ie not shelf store oil,need special oil thats high in zinc and phospherous)

Stick some bolt on TPI or aftermarket intake on it of some sort and with headers it should break over 300hp crank easily. I dont know how good those stock GM 190hp heads are but I think they are the 76cc stuff and small valved. L98 iron or even the vette aluminum L98 heads are much better castings.

 

Do you have a roller block?

 

No its a flat tappet

 

 

Nos is out of the picture

 

then how about Zex or Nitrous Express ? It doesn't matter the brand but I've not heard any complaints about NOS units.

 

Lol I see what you did there and I like it.

Also, I suggest zz4/corvette 113 heads and an xe268 cam.

 

I will rephrase. I don't want nitrous.
