I'm going to swap a 350 TPI from an 89 Corvette in my 1987 Iroc-Z. I will have about 700 bucks left.

With that budget, what would add the most HP?

 

a good tune up, and also make sure you run the correct prom in the ecm for a 350 aluminum head l98, might want to add some headers if you don't already have them while the engine is out

 

I agree with the headers, and would also suggest the SLP runners to get her to flow a bit better up top.

 

Oh alright. For the tune up what would you suggest for plugs and oil?

I was thinking of the edelbrock high flo runners, which one's are better?

 

If I remember right the SLP are cheaper I think. Tune up wise, I like to stick with the proper AC Delcos for you engine. Oil wise I like Royal Purple.

 

Oh alright. I wanted to do Bosch plugs and mobil 1 oil.

 

Id get a set of the Hooker 2055's and get that sucker welded
up to a nice sounding muffler and you'd still have about $300 or
so bucks to work with!

..or you could use the $700 to go long tubes headers true dual,
that way for ready for a 500HP small block when the time comes!

overkill I know!

Id get some Hookers or the Hedman's!

 

The Bosch plugs are garbage IMHO. I had the platinum's in mine for awhile, and they were crap! Went back to the stock AC Delco and the car ran aces again.

Oil isn't a huge issue as long as it is good oil and not some generic crap.

 

Oh alright sounds good. Idk what do about headers since I'm in California, will it pass the smog?

 

You can buy headers that will allow all the plumbing from you emission to hook back up to them. But I am not sure who sells them. Someone will chime in with a part number for you I am sure.

 

Oh alright sounds good, I'm probably gonna go with those hooker 2055's.
