Tech Question
Glenn Lackey, Burley, ID, 1971 plymouth Road Runner 440
Rick....I appreciate your rag, great articles. (I'll avoid the "20 questions", even though I have several); My 440 is bored .060" over, supposedly has a 270H cam, TRW slugs, stock heads, 4-speed; I put a Holley 770 on. Should I swap to a double-plane intake? (mine is the Torker single-plane); I'm not racing or running at high RPM. If so, what intake do you recommend?
If the engine neve sees over, say, 5500 RPM, then a dual plane would be a slightly better choice. But since, with such a mild cam, this engine probably has torque up the yazoo even now, I don't think the swap would be worth the hassle or expense.
If you do go ahead, there's not a helluva lot of difference between any of the intakes, even a stock iron one is fine. The old Edelbrock CH-4B did a good job, as does the MP M-1.
