RedTop Engine?

[Mux213]

Nohachi,

yeah thats the weird bit, in theory the tvis idea in combination with the big port system should always produce a higher power curve then the small port engine. But they say that the better flow of the smallport combined with the cams just make it a better design then the tvis/bigport engine but that it looses in revyness and responce due to the heavier parts used in the stronger underblock.

What is actually true?!!? I haven't driven a stock redtop engine and compared it to my bluetop to actually find out, nor seen a dynosheet. It would even be kinda like comparing appels with pears. Is the difference the head, the block, or all the other bits.

What you really should do is take a 3rib block, dyno it with a bigport head, then dyno it with a smallport head, and find out which head really performs better.
Then do the same with the 7rib block

Probably someone has already done this.

For now, I simply keep to the rumor, redtop engine gives more power, bluetop engine is rev happier.
