Advise on Ford 302- 331/347

[zarpoxx]

Hello

I wanted to know your opinion about the following topic:

I have a cobra with a 302 ford engine (1971), with edelbrock intake (dual plane), holly 650, and little else (stock pistons, stock camshafts, stock heads).

I wanted to increase the performance of the engine (supposedly gives 324 hp, I don´t dyno the engine, so it is a estimation that the seller told me), and wanted to know your opinions about what elements to install keeping in mind that in the future I will want stroke to 331 or 347.

I know I want to buy AFR heads (I know that if I were not to do stroker the best would be 165, but I wanted to know that you advise me in order to be able to serve both the 302 engine and the future 331/347 if it is possible.

Camshafts that are worth for both applications? (model or specs if it is possible?)

My current status is:

Differential 3.31
Gearbox tremec T5 (first of 2.95 and fifth of 0,73)
15 "wheels (215/60 15 and 235/60 15)

The use is 100% street (mountain ports and sports driving)

I would like it to go up to 7,000 rpm and have torque from below (say 1500 rpm - 6500 rpm, but could reach 7,000 rpm)

I would like to get in the 302 configuration up to 400 hp at least to the flywheel.

I would like to arrive at the 331/347 up to 500 hp at the flywheel.

Thank you so much for your opinions, are much appreciated

A greeting from Spain!
