Since you are on a budget just have them do you a short block,$450-$600 stock stuff.
Buy some good used heads or new gt-40's.E-7 heads are just too much work to make them
a serious power contender,LOL!!
The bottom end can easily handle 400-500 hp with occasional power spurts to the track.
You can build a budget motor easily for $1500-1800. Probably get you in the 300 hp range.
Add a blower or turbo down the road and you will get 450 with ease.
No need to go all out unless you are a serious racer than you need more qaulity parts!!

i would go for some gt40's. they are better than the gt40's because of the spark relocation. just make sure to get some spark plug wires with long boots because the normal wires will get burned because of the spark plug being too close to the headers.

For reference, I bought used GT-40's off a 93 Cobra for $250 and a 94-95 Cobra intake manifold for $300. These two components alone dropped my 1/8th time by 0.36 and picked up 6mph. DO NOT ORDER A CHIP. Most aftermarket chips are junk. You may not even need a tune. You can keep your stock 19lb injectors for now. They're good for 300hp(fly). Fuel pressure regulator is fine too. But I would buy a 190lph fuel pump(stock is only rated at 88lph). Since you'll have the heads off, I'd buy some cheap headers and throw them on. The stock headers are badly crimped. You'll want as much flow as possible. For a cam, I'd go with the TFS-1 cam or keep your stock one for the great low end torque(stock cam is also boost friendly as is the TFS-1). But when upgrading to a new cam, you'll want higher rated valve-springs. The stock springs are barely adequate for .500 lift. Most mild cams make in excess of that.
