gears and a short throw shifter are always good. underdrive pulleys are useless. exhaust is ok. the PCV breather setup/catch can is good to help prevent motor damage, but won't give you any extra power. Weight reduction works well. The mod motors themselves really don't need much. Fully ported heads/intake with cams can net you some good gains, but depending on what you do a blower or nitrous is more cost effective. The rods/pistons aren't great either.
why u say underdrive pullies are useless??? they are proven as a power gain.
only on a dyno is the gain noticeable. there are no benefits to running them and mod motor cars need to be kept cool and they are known to create cooling and charging issues. Its a waste of money.
I wish I saved up a good amount of money for a short block instead of doing random mods. personally I do not care how my car handles being an automatic. So lowering springs were a regret. shorty headers weren't worth it in my opinion horsepower wise but it kept the motor a little cooler.
mods I like but are limited to the motor are... p:p heads,comp cam 270's,p51 intake,75mm tb, full length exhaust "longtubes" and 31 spline axles with 4.10s also UPR coil over with no sway bar. Last but not least a dyno tune wet kit. only because their in hudson and give a 25 percent discount in cash.
I'm curious 01sivergt ... how is the daily drivability and gas mileage with 4:10 's and a 4000 stall converter ? Underdrive pullies and a TB ( throttle body ) are worth what ?.... 15 horse at the most by themselves . You would never feel that in the seat of the pants . However they could be complimentory to other bolt on's . Not everyone has the kind of money to buy those high dollar parts you recomended . I'm not saying there not good mods ... they are ! But 600. for cams , 12 to 1700. for heads , a 1000. for the p-51 set up and so on . If I was to modify another mod motor again .. All I would do to it is ( budget is a factor of course ) drop in a a forged and stroked short block and either an F1A or a single turbo with a quality fuel system and air meter . You can easily make 5 to 600 rwhp and the drivabilty and fuel mileage would feel like stock ... till you stand on it !! I'm not saying this is the only way .... just the way I would do it .
when I finally have the money to put a 5.1 in the car. I WANT A F1A bad... everyone likes turbos or kb,whipples etc. Before i cam and headed my car I almost bought a ps-1 or whatever the hell you call it. Bottom line is whats the point of running a blower when you can only tune for 360-380 horse through an auto. So basically im hoping when my motor goes its just a burnt piston. comp 270's work well with blower cars. so basically n/a im putting down 294rwh/288 trq. on the juice I made 370rwh 390rwtq. I pull -10 degrees out only for a 125 shot. 26 na/ 16 on nitrous. my car has 42k on it and runs well. and TB can make power but its highly recommended you go 75mm. I have one on my car. To your last question about gas mileage+drivabilty. The converter is loose, take's a little time learning how to drive with it. If your on the throttle to hard to fast before you alow the converter to lockup "D" or "OD" the trans will feel like its slipping. 1st and 2nd does not lock part throttle. 2nd only locks wide open. I went to maine and back, Car went to 230miles to 13.5 gallons 16-17 miles to gallon. Now that its hot with ac im sure it will be less. I do 72 mph around 2700 rpms.
mike dez built a 2v stroker blower car. 800rwh 22psi 20degrees of timing stick car with race gas. I'f I had a f1a I want atleast 650rwh through an auto. and 750 with race gas.

I think your talking about Adam's 03 GT . That car is pretty sick !! I went for a ride in it last year and can tell you ... HOLY SHIT !!! He has alot of mods on that car . Alchol inj. stage 3 fox lake heads , sheet metal intake and so on . Not to mention the F1A !!
Oh and pretty good mileage for 410's through an automatic and a 4000 stall converter ! I was thinking around 10 miles to the gallon ... LOL !
yea it averages around 15mpg. I love your buddy adam's car. Cobra's are awesome out of the box,with a kb or whipple that almost unbeatable.... but building your own unique car like yours or adams is way cooler in my opinion. why follow the pack when you can lead it.
maybe more throttle response but no power. If so, your the only one out of hundreds of guys i know that got power from those too.
Pulleys are a waste too becauseif you want to blow or turbo your car you have to take them off. Waste of time and money.
Unless you want to look pretty and gain "10hp" then save your money for something good.
Half ass mods= not even worth it(Budget racer). Just save and go big
Ok ! I'm a little confused at your point ... You stated underdrives make no power . Then you go on to say they only give you 10 horse ! You do have a point about it not being a good idea to run underdrives with a blower .... But it will not effect a turbo . If anything ...they would help by letting the engine rev faster and hense spooling the turbo faster . Remember a turbo is not driven by the belt . On a final note ..I think that everyone know's that underdrives are not going to make your car do wheelies . But for the money they cost and the simplicity of instalation ... 10 horse and a little better gas mileage is pretty good in my book .
Well, since I think that Steve's post was at me.... I have an 03 cobra and the pullies are an idler and 2.76. That along with the singleblade TB did a whole lot of power making.
