ya congratulations domestics run faster superstock times
i agreed now i hope u can sleep better at night,
but a import needs less power to go fast
on average they are much lighter than a v8 car and so much less power is needed.
like a 1967 camaro ss 350 was rated at like 275hp (correct me if im wrong) and they run 15.4
(http://www.albeedigital.com/supercoupe/articles/0-60_Quarter_Mile_Times/C_0-60times.html)
1992 180sx runs sr20det was rated at 205 hp and it runs 14.8
its all about hp/weight ratio right
but im tired of arguing with you.
so we'll agree to disagree.

but anyways i havent seen you before, so are you putting a LT1 in your blazer or what?

another thing you want to look at is the tires used. back in the 60's you could only run a 6" wide tire (nhra rule). period. and if you take todays tire and put it on a stock muscle car you will pick up close to 1 sec. if you want to compare muscle cars then actually pick a muscle car not a pony car there is a diffrence. im not saying that you cant get decent numbers out of a import im saying that you have more potential with the V8. with enough money you can make anything fast. its just a question of consistancy/dependability/price. so many people want to have the best and spend nothing to get it. thats not going to work (if it does it wont for long) i have a friend at work that has a spyder eclipse and he bought a boost controller and a few other smaller things (non performance) and with a stock fuel system and engine internals hes going to crank up the boost to 16#. it might run a lot faster then it does now but how long do you think that will last before he blows it up? then hes gonna have to spend the money to fix what he broke when he cut corners. how is this going to be cheap or dependable ? id also argue street manners with a import vs a domestic. imports are just as bad as domestics.

ya well i can agree with most of that.
the thing most people do with their boost controllers is just turn them up when they are going to the track
if you leave it cranked it will for sure lower the length of that engine by quite a bit
prob by about half i would say
that car will last 100k at max boost instead of 200k (obviously just a guess but prob somewhere around there)
and whats the street manners?
you mean like how well a big v8 does as a daily driver?

and u never answered if your putting a lt1 in your truck or not :(

haha nice arguement guys... as for my truck

its being parked next year... its going to be a cruise truck for sunny alberta
i've seen what superchargers can do to my truck. its an suv, it doesn't need to be going THAT fast. a setup for a 6psi wynjammer supercharger w/ tune would cost me about 3000. with a shift kit, 4l60e should be able to take that. the blazerbeam is going in for an engine rebuild in a couple weeks, forged pistons, cam, shift kit and headers. i'm not worried about it being as dependable as it is now because its not going to be my primary vehicle. also, i've seen this supercharger set up slay a 350 swap

that paint job is close to what i want to paint my judge. i love that color. i want my GTO to have a little bit more of a yellow tint to it. the street manners thing i was reffering to is with a V8 vs a import (boosted) you will have diffrent issues to deal with for each one. i dont knwo what MPG a import with some mods and higher boost will get Vs a V8 but im sure when you get closer to 15-20# of boost you need quite a bit of fuel to compensate for the air/fuel ratio. i wouldnt mind expierenceing a boosted vehicle. i have a 327 thats going into my C10, my gto has a 428, my first car was a GTA ive always had a V8 with the exception of the blazer. i wouldnt mind finding a syclone/typhoon engine and driveline and putting in the blazer if its possiable. would the vortec heads flow better then the stock sy/ty heads ? are they compatiable?

Moar powar is goooood!
However, the imports have WAY better gas mileage in high HP areas

Usually.

Other than the HO Quad 4, there hasn''t really been any impressive N/A 4 bangers from North America... These days it''s not much, but back in the late 80s/early 90s when it was made...
That being said, like it''s been said, it all depends on what you want to do...

Heck, for my play toy car, I want an ''85 Toyota Corolla with a TRD engine.... 240 HP 173ft/lbs of torque... Redline of 11k RPM

In a car that weighs maybe 2000lbs...

frankly i think you guys got way off this guys question v8 will be about the same price with pretty much the same results if you have the right resources and know how to shop go v8 then you can still do alot of crap later on

as for you guys argument i met a guy that had an eclipse he spent $12000 grand and was pulling mid twelves i also met another guy that had a malibu chevelle with a 400 sb built the car for shows not races and was pulling in the high 10s low 11s on $11000 so trash the weed eater on crack and just get american muscle if you want speed and save some money too
